Toon Shader Ten update

Color matching from Concept paint over

My Recommendation

The problem with the highlights is they aren't as controllable as they would be with other lights... 
I can talk to you more about it. 


This isn't quite the final for A00, but Johanna asked if I would upload it.
So here it is

Check List for Lighting (General)

Courtesy of Garrett Hoyos

A few things to make sure you guys are doing: 


1. Make sure PBR is turned on (PHYSICALLY BASED RENDERING)
2. Make sure GI is on (AKA DIFFUSE LIMIT SET TO 1 bounce) 
3. Motion Blur are turned on as well. (Motion Blur Checked on, Xform & Geo Time samples set to 2 for linear movements, and 5-8 for complex things like arms swinging/spinning, etc. 3 is a good default. 
4. Make sure all your geo is being subdivided by defaullt. (in the geometry render subfolder of each piece of geometry check the "render poly as subd). 

My process I learned from blue sky:
Light the environment first. Then the characters. If the environment doesn't look good, the characters won't have a chance. Render the environment separate from the chars. 

The characters need all the focus on the head and eyes, you don't even need the environment in the character rop at all. Light it so the characters POP out of the environment. Make sure you don't leave the underside of the face go to black. It should be lifted w/ a bounce light. Eyes should be the main focus. Have a separate light for the eye spec hit. 

Have 2 separate mantra rops. Env and Chars. Then have a 3rd mantra rop for character shadows (environment will have a new material on it only for accepting shadows, chars are set to phantom). The shadow render should be pretty fast in comparison since it only loads geo & 1 shader. If you need help figuring that out let me know. 

Use Light blockers like circles (flat disk) or grids to direct the viewers eye to the characters eyes. Set the light blockers to phantom in the ROP. The other option is to use dappled lighting textures - set the texture map on the light w/ a map to make the lighting more varies, instead of a constant light, you get variation like what happens in real life. 

I typically won't add color to my lighting until I have the values down. The values will be the true test if your lighting holds up, color only give it more life. Contrast/Value will be the key, so eliminating color at first will give your eye some room to see. Also, flipping the image horizontal or vertical is a great trick just like a painter, to reset your brain. 

When I light I will do it one light at a time. Singling out the light will allow you to see what that specific light is affecting. I'll turn each one on, make sure each light is doing what I want, then turn them all on.

Rendering in Layers Cheat Sheet

So for everyone who came today, thanks for listening! Hopefully that made sense for everyone. Here's a link to a handy powerpoint that will help you use the dusk mantra tool. It's a little dated but it explains everything pretty well. But here's what you might want to know:

Forced Matte: Object "cut out" of the other objects behind it in the scene.
Forced Phantom: Remove object but calculate reflections/refractions/transperancy as if it were still in the scene
Exclude Object: Completely remove an object from a render
Exclude Light: Completely ignore a light in a scene

If you're rendering that means there will be some baby sitting. That's why I recommend Solitaire to all of you. Here's the time to beat on freecell: (1 min 59 sec)

I'm sorry, Nathan made me do it. . . ;)
