Who Are You?This is an update of the first CGI image I ever completed in DAZ Studio.  Back then I didn’t know how to do lighting so I moved the character into the lights that were already pre-built into the set.  This is the original:

v6 test 09 cam 01It took me days to place the character properly and learn how to aim a camera and render.  The image is dark and I’ve grown to hate it as I’ve become more experienced.  And so, like George Lucas, I decided to go back and change my earlier work to add new characters and “make it better.”

Back to the Beginning

I loaded up the old project and continued right where I left off.  As I re-familiarized myself with everything it became obvious how little I knew at the time.  It was interesting to see how I solved problems back then.  I’m really deep into all the technical details now and the way I work today isn’t necessarily better, just more complicated.  It was surprising.

I knew I wanted to add more light and make everything brighter, but what else?  I hate pieces where people just stand there so I added another character for the girl to react to.  She’s looking out a doorway so I put a little alien guy there who is startled by her.

I tried many camera angles to get the best interaction of the two characters but eventually decided to keep it wide and head on similar to the original.  You need to see the distance between them for it to work.  These are some of the test angles.

v6 15 cam100 possible angle v6 15 cam103 possible angle v6 15 cam101 possible angleThe last one isn’t bad but you can’t tell the alien is a tiny guy.  I think you need to see that to understand he is scared.  The middle one’s good too but you don’t get the sense of him coming around the corner.

Straight on wide shot seems the best but I still think it’s boring and too far away.  Will have to work on that in another piece.  For now it will have to do.

A Brighter Future

If I knew how to use an ambient light back when I originally rendered this scene it would have looked much better.  I’m a big fan of the Advanced Ambient Light by Age of Armour.  It’s the easiest fill light I’ve ever used and it renders fast.  While I was playing around with it, I tried something new.  I set three ambient lights in the scene.  One was set to light everything overall like I usually do.  The other two were placed very close to the characters with the light limited to their immediate area.  That gave me the ability to adjust the brightness of each character and the background separately.

v6 12 cam07 00 amb key 2 meters around character 100 percent + amb fill 40 percent v6 14 character ambientIt worked out very well.  The light from the stairs and the blue back light from the windows were still the main lights but the ambient lights in this configuration allowed for very fine brightness adjustment during the final tweaking.  I’m going to use this technique whenever I work in 3Delight.

The Small Stuff Is Always the Hardest

The most difficult part of this re-imagining was actually the back wall.  The set had a window that looked like a portal or hatch right where the lines on the floor converge at the back.  It drew your eye right past the two characters to the window.  I had to eliminate that panel and take a different wall from another part of the set and replace it.  The other wall had a larger window that extended behind the corner so it wasn’t as distracting.  Finding the right panel to use took some time.  Adjusting the glossiness of the window and darkening it with a semi-transparent black plane helped too.

v6 15 back wall 01 v6 15 back wall 02Know Yourself

After struggling with the complexity of Iray for the past year it was a joy to build something in 3Delight again.  You forget how simple it is.  And that’s the key, isn’t it.  Simplicity.  Working in this old project, I was surprised how much I was able to do originally with how little I knew.  I didn’t have a lot of options – not a lot of knowledge about surfaces, materials, render settings, shaders, UV maps, morphs, or even lights.  I didn’t have all those things in my head slowing down my creative process.  I just did it whatever way I could figure out in the moment.  I’ve forgotten what that’s like.

Not What I Thought 2016 BTS 00 lightwaveI encourage everyone to do this at least once.  Open up a really old project and see how you used to work.  See how you used to think.  You may learn something from yourself.

Alien Avatar

Aien AvatarI started a facebook page for my artistic work several years ago.  Ever since then I’ve wondered how to separate what I post to my personal profile, which I keep essentially public, and what I post to my page.  After years I still haven’t figured it out.  The page is reserved for my work and general SciFi culture, but I also post that stuff to my personal profile too, so I end up cross sharing a lot which I hate.

It’s easy to get confused between the profiles so I make sure they at least have different avatars.  I created this one similar to my new personal avatar but with an alien.  I won’t know what to post where, but at least I’ll know who I am when I’m posting!

Eye Light

I had to light this differently from my personal avatar.  Usually I go for the control of spotlights but for this I needed something to reflect in the big black eyes.  I lit this image solely with a skydome that surrounded the entire scene.  Since that put too much light on the back panel, I then modified the surface and made it darker, so it would look similar to the original background.

My quest for the perfect CGI avatar

After using my new CGI profile picture on facebook for awhile I started to dislike it.  It looked mean, especially at small sizes.  Part of the reason I think was the contrasty film-noir lighting.  I thought I would try something a little different with softer light.  I also turned the face to the side similar to my original photo that I used for years.  This is what I came up with.

The Future ContinuesI started to dislike it as soon as I uploaded it. I thought the face looking away from the text had an aloof quality. I turned things around, used a longer lens so the face wouldn’t be so distorted, and gave him some hair. This is my newest avatar.

The Future DirectionI’ve been using it on facebook for about a day now.  So far I like it.  I’ll upload it to other social media sites and live with it for awhile.

Color Correction Test

Run (CC test)For most of the films and television shows I’ve worked on the goal of color correction was to make the picture look technically correct and pretty – healthy skin tones, bright colors, maybe a bit “hyper real” but still normal.  Anything that degraded the image was bad and needed to be fixed.  What I’m trying here is relatively new to me.  I want something more stylized for this animation.  I’ve thrown in some grain and even a faint hint of scan lines to roughen up the super clean CGI.  I’ve also washed out the skin tones in favor of the blue and orange.  For comparison here is the original render before color correction.  (Click both to embiggen.)

Run (no CC test)I’ve been using the CC tools in Lightroom for most of my CGI work to date but since this is an animation I’m using the tools in Adobe Premiere.  I’m finding it much harder.  I love the CC tools in Lightroom.  They’re more intuitive than the controls in Premiere or photoshop.  I wish Adobe would create Lightroom style CC tools for all their products.

If this were a still image I probably would have gone a lot further with the grunge but it has to work as an animation.  It has to look good in motion and on all the other close-ups and wide shots too. I’m pleased with it right now although I’m a little concerned that the grain will be lost when the video is finally compressed and uploaded to youtube.  We’ll have to see what happens.

The Future Starts With You

The Future Starts With Youout of focus art SQUAREI’ve been using the same avatar across all of social media for many years.  It’s not very good.  If you look at the original it’s actually out of focus, but you can’t tell when it’s a teeny tiny avatar on facebook.  My wife CAT is in it too, which is nice.

I always intended to replace it but it was working, doing it’s job, so I didn’t.  When I shaved my beard over a year ago I thought, “Well now it doesn’t even look like me.  I really need to make a new one!”  But it was still working.  People still knew it was me.  So I didn’t change it.

Cut to a few days ago.  I was in DAZ Studio and I decided to experiment with different ideas for a new avatar.  I figured I could come up with some “concept art” and then take a picture of myself with the same theme, same lighting.  Simple.  Maybe even use the same CGI background so I wouldn’t have to deal with that in the photograph.  But, what to do?

What Makes a Good Avatar?

To all those people who have their kid, or their dog, or cat, or a movie star, or an anime character, or their feet, or a sports team logo, or Abe Vigoda in their avatar:  Nobody can figure out who you are!  I go through this all the time.  The name sounds familiar…  Did I know this person in college?  Did we grow up together on the same street?   Did we work together ten years ago?  Is that YOU as a kid?  Or is that YOUR kid?  Now I have to be a detective.  It’s frustrating.  Put your friggin’ face in your avatar!   /rant

Square One

I like an avatar with a big face so I started with that.  The bigger the better because sometimes these things are super small.  I decide to try something similar to what I have now, an evolution if you will – the same but better – a big face but a little arty and off to the side.  Centered is so boring.  I used a long 200mm lens to blur the background, making the face stand out.

The Future Starts With You BTS (mesh)I decided to go for hard side light with a blue kicker (back light) to give it a shadowy tech-noir feel.  I wanted the style to reflect my personality.  I’m one-hundred percent SciFi and my avatar should be too!

Reality Is an Illusion

I then spent a lot of time trying to get good skin.  There’s a trend in CGI these days.  Reality.  I think reality is overrated but in this case it makes sense.  An avatar is supposed to represent a real person.  …And it doesn’t hurt to learn new things.  I spent a lot of time experimenting with skin translucency, glossy reflections, roughness, bump maps, and scores of other surface controls.  Endless tweaking.  (Welcome to CGI.)  Ultimately I got something that looks like a real person.  The guy doesn’t look like ME, but he looks relatively real.

And then I put a glowing cross hair in the eye.  Screw reality!  I like robots!

The Future Starts With You BTS ccAbout-Face

And here it is.  It turned out much better than the “concept art” that I intended so I’ve decided to use it straight-up as my new avatar.  So to the people who have their kid, or their dog, or cat, or a movie star, or an anime character, or their feet, or a sports team logo, or Abe Vigoda in their avatar:  I’m now one of you!  My avatar is now a synthetic man that doesn’t look like me.  If you can’t beat ’em join ’em.  We’ll see if it works.

Frozen In the Life I’ve Chosen

Frozen In the Life I've Chosen 10KI was testing out special snow shaders I purchased and decided to make an image of frozen pants.  Why?  Well, a fellow discreet logicD/Vision editor from back in the day, Tom Grotting,  started a trend in Minnesota.  He freezes jeans and stands them up all over town.  It’s caught on in other places this winter.  Check it out.

In my image, special shaders called Let It Snow created the snow on the pants and the tops of the mountains.  It took a bit of fiddling but in the end it looks quite good, at least from a distance.  The shaders are added to an invisible shell around the object and if you look very close, especially along the edges, you can see the shell and the snow hovering above the object.  You can shrink the shell but that changes how the snow looks across the surface so it might be a bit of a compromise to get the right look.  I set the mountains in the background a bit out of focus which helps.  All in all though, the shaders work quite well.  What do you think?

Animating a Complex Camera Move In DAZ Studio With keyMate and graphMate

This is the video that goes with my article in the December issue (#18) of DS Creative magazine.  My in-depth tutorial was based on this shot.  Check out the article on page 72.

I originally developed this shot to test a complex keyframed camera movement in DAZ Studio.  So far it looks like the DAZ software will be able to do the kind of animation I want to attempt.

No One Told You When To Run

No One Told You When To RunI’ve been spending the last few weeks experimenting with animation making a few test shots of people running down long hallways.  I’m going to put them together and make a short video but I want to add sound and music so it’s going to take a few more weeks.  In the meantime, I found an interesting frame in one of the animations and set a camera for a still shot.

Fast and Hot!

This piece is rendered with nVidia Iray which I’m still learning.  It took about five hours to render which is considerably faster than my previous high-rez image which took a full twenty-four hours.  Why was this one faster?  I bought a GTX Titan X graphics card and added it to my system.

EVGA GTX Titan X croppedIray can use both the computer’s CPU and the graphic processors on the video cards to compute the render, eliminating the need for a render farm.  (…at least for now.)

I managed to get my old Quadro K5000 and my new Titan X graphics cards to both work in the system at the same time, which some say can’t be done because the drivers conflict.  So far it’s working for me and both cards chug away when building the image.  The new Titan X ended up doing two and a half times the work of both my old Quadro K5000 graphics card and CPU together.  It’s a significant boost but boy the Titan X runs hot!  It screams at eighty degrees Celsius while building the image.

V6 runs - rendering heat monitorIt turns out that if I render with the door on my computer closed, the Titan X throttles down because of the heat.  I’m going to have to build a custom vented door for my system with maybe a fan or too.  For now I’m working with the door off.  At least I won’t get cold this winter!

Don’t Go Too Far!

I had two major problems with this render.  The first was a strange shadow around the eyes caused by the photometric fill light I was using on the character’s face.  It was as if the spotlight didn’t see the transparency part of the lashes.

V6 runs 07 ECU2 frame 305 disc key light - eyelash and hair shadowTurns out this was a combination of increasing the size of the light making it soft, and the distance the character was from the center point of the CGI world.  It’s a crazy bug that DAZ3D has promised to fix in the next version of DAZ Studio.  In the meantime, I had to grab the entire scene – sets, cameras, lights, everything – and drag it all back to world center.  Thanks to everyone on the DAZ forums for helping me debug this problem.

Strange Honeycomb Dot Pattern

The other issue was a strange honeycomb dot pattern appearing in the wall texture.  (click to embiggen)

V6 runs 09b wall problem 01Looks like Iray was compressing the wall textures too much.  There’s a Texture Compression setting under the Render Settings / Advanced tab.  I had to raise the Medium Threshold to 2048 and the High to 4096 to make the problem go away.  Apparently this increases the RAM needed on the graphics cards during the render but my system didn’t have a problem.  It also didn’t effect the speed of the final render.  I know because my system built this image twice!

My Only Hope Is an Alien Weapon

My Only Hope Is an Alien WeaponI started this scene with the intent of making a simple header for my facebook page.  A reclining figure fit the aspect ratio so I started there.  The rest came from that.

I also decided to use this piece as my first serious plunge into DAZ Studio’s new Iray render engine.  I have been avoiding Iray since my first experience showed a significant increase in render times.  I was right to be afraid.  The original render of the image above took 24 hours to cook.  But I’m skipping ahead.

A New Facebook Header

For the lighting I decided to keep things as simple as possible and use the light built into the ceiling of the set.  I changed the light fixture material to emissive and started the guesswork of how bright to make it.

Zorn BTS ceiling lightBeing a newbie, it took me awhile experimenting with the various controls.  The f/stop in the camera doesn’t effect the exposure, only the depth of field but unlike 3Delight, there are exposure controls called tone mapping in the Iray render tab.  For some reason the defaults are shutter speed 1/128, f/stop 8, and ISO 100.  It seems to me that would give you a dark photo even outdoors in bright sunlight.  I’m also not sure why you would change one setting or another.  If changing the f/sop doesn’t change the DOF and raising the ISO doesn’t increase grain then why have different settings?

I’ve seen a few online tutorials that say you should raise the luminance of your indoor lights into the millions of lumens.  That is extremely bright and seems wrong to me.  Why have real world units like lumens with no connection to real world light levels?  Anyway, I spent a day fiddling with all the various controls and eventually settled on something that looked properly exposed.  In the end I decided to follow the advice of the tutorials.  I kept the render exposure settings (tone mapping) at default and set the ceiling material to 2,000,000 cd/m^2 luminance units, which is excessively bright for room lighting.  But the final image looks correct.

Fill Light

Since the light is all top down and my character is wearing dark clothing I needed a little fill for the underside of his body.  At first I tried using a spot light.

Zorn BTS spot fillFor some reason the emissive mesh lights do not show when you are in working mode in DAZ Studio, only the regular lights do.  So to balance the mesh ceiling light with the spot fill I had to render each time I adjusted the light.  This became quite tedious since you really couldn’t see any of the nuance in the test render before ten minuets or so.  Here’s an example of a screen test render after about six minutes.  It’s still hard to tell what’s going on in the dark areas.  (Click to embiggen and see the grain.)

Zorn BTS grainy full with timeI abandoned the spotlight fill idea and tried what I would do in real life in this situation, which was to use a white bounce card.

Zorn BTS white cardIt worked but unlike real life I wasn’t able to subtly position the card to get the reflection going exactly where I wanted, again because there isn’t any live feedback from the overhead emissive  light.  My character was still slightly dark on the bottom but I fixed that in color correction.

Facebook Render

My first renders for the 851×315 facebook header ended up a little grainy with the default settings so I raised the max render time and max samples and was able to get a final result with 95% convergence.  I think this took a couple of hours.  I don’t remember.  All I remember is that it took a lot longer than I thought it would for such a small resolution.  My system can render the same 851×315 scene in 3Delight in a minute or two.

My Only Hope Is an Alien WeaponAfter I posted the image to facebook my wife CAT mentioned was that the red in the back might be too similar to the orange in the character.  Since I wanted to eventually render this scene again at high-rez and make something suitable for framing, I also decided to try and change the red elements in the set to blue.

Paint the Set

Up to now I have avoided directly editing the textures in a model mainly because there are so many other things I have to learn in CGI work.  I’m very familiar with photoshop editing.

Zorn BTS blue texturesChanging the color of the background set surface textures was easy although a simple color conversion left the set a soft baby blue which didn’t really fit the theme of a gun battle.

Zorn BTS white card 2Individually adjusting the darkness of the various blue elements I was able to balance things the way I wanted.

Zorn BTS blue redAt this point I set a new camera with an appropriate aspect ratio, set the resolution to 10K and hit render.

One Day Later…

As I mentioned above, I rendered the 10,000 x 6667 image for a full twenty-four hours.  Well, I should say the FINAL render was twenty-four hours.  I did a lot of test renders at various resolutions including 10K, 8K, 4K, and 1080HD.  This took a few days.  Most of the tests I set to time out at fifteen hours since that’s already more than “overnight.”  They were all a little grainy but not bad, perhaps similar to something shot on film.  I was able to get 95% convergence in fifteen and a half hours at 1920×1080 HD resolution.  That’s the resolution I would use for animation and that’s just way too long.

This picture shows the grain at about twenty minutes into one of my Iray render tests, which is about how long one of my 10K 3Delight renders takes.  I believe this one was 8K.  (Click to embiggen)

Zorn BTS grainy faceI’m hoping that there will eventually be a few ways to speed this up.  I’m guessing that the emissive lighting used here takes a lot longer to render than lighting with spot lights.  I haven’t tested that yet though.  I could also throw more graphics hardware at the problem but my computer is no slouch as it is.  All the work I’m describing here is on a dual eight core 3.1 GHz Intel Xeon processor system with 128 GB RAM and an nVidia Quadro K5000 with 4 GB RAM.  The render logs say my CPU’s are doing a little less than half the work so I’m guessing installing two more graphics cards (maybe nVidia GTX 980s?) could double the speed.  So that means a 24 hour render could be done in 12 hours, still a long overnight render.  And how much heat will build up in the case with three graphics cards?  I don’t know.  I need to do more testing.

The Final Picture

The final render is still a bit grainy even after cooking a full 24 hours.  Click the image below to see the 10K image at 1:1 pixel ratio on the left.  The complete image, however, has enough resolution that it looks pretty good.  I’m quite happy with the light too.  I didn’t do much color correction on this one, just brightened up the shadows and color a bit.

Zorn BTS lightroomIray is still a big question mark for me.  I got into DAZ Studio because it made CGI easy which I felt could make it possible for one person to do short animation projects.  Iray makes everything harder.  It takes a lot more time to light.  You have to essentially work in the dark if you are using emissive mesh lights.  You have to futz more with all the material settings on the models.  And the render time is a killer, not only at the end but throughout the process as you are changing things and checking your work.  For my first steps into animation Iray is probably going to have to take a back seat.

Stepping Outside She Is Free

Stepping Outside She Is FreeI’ve been wanting to do a “big character” for a long time.  CGI scales easily so I thought it would be simple.  Well, the scaling was simple, then I needed a city so you could tell the character was twenty times normal size.

urban renewal

I used Stonemason’s Urban Sprawl 2 The Big City which is absolutely fabulous.  Once I found a good spot for the “incident” I needed to add some buildings and extend the street another block or so in the background.  I also moved some buildings around and shortened one in the back to get the skyline I wanted behind the girl.

Big Aiko BTS - city 01Big Aiko BTS - city 02I’m tremendously impressed with Stonemason’s work on this city model.  It’s incredibly detailed with 20 or so different buildings – lots of props like streetlights, signs, mailboxes, and trash bins – and yet the model is very light.  It doesn’t slow things down that much even when you have all four city quadrants loaded as I do here.

bad skin

The scaling of the girl created a problem I didn’t anticipate.  When I started lighting I did a screen render and the skin was all messed up.

Big Aiko BTS rendering SSSI tried different skins and some were better but all seemed to have problems.  I eventually figured out that the Subsurface Shader (SSS) was the issue.  Apparently it didn’t scale well.  While I was trying to fix the problem I discovered that it got better if I added in HD details.  The character Aiko 6 doesn’t have an HD add on so I tried adding the Victoria 6 HD details.

Big Aiko BTS - V6 HDThe screen render turned out better but there was still some problems as you can see here on the arms.  (click to embiggen to see the issue)

Big Aiko BTS - HD skin renderIt turns out though, that the problem doesn’t present itself if you render it out huge (at 10K) which is what I always do at the end anyway, so I stopped trying to fix it.  The final render came out fine.

crazy pants

This was a most annoying problem.  Every time I closed the project and re-opened, the guy’s pants over on the left would go nuts!

Big Aiko BTS - normal pantsBig Aiko BTS - crazy pantsNow maybe this was because I had Genesis clothing on a Genesis 2 character, but I’ve done that before and I’ve never seen this.  It’s the Morphing Business Suit on Gianni 6.  Never found out why this was happening.  The only solution was to delete the pants and re-load them onto the character.  That worked at leased until I closed the project and re-opened.

big finish

For the final color correction in lightroom I decided to pump up the color on the main character while keeping the city bland and gray.  What do you think?
