On Unity 5.0's new deferred renderer

Among the many things coming in Unity 5.0, I am most excited about the new fat g-buffer deferred renderer. However, some things will need to fall into place for me to take full advantage of its power:

  1. It must allow me to override the lighting shaders, like I can now.
  2. It must let me, at a minimum, store a single low precision custom channel in the g-buffer so I can pass specular occlusion to the lighting shaders.

If I can't pass specular occlusion, then I won't be able to support proper per-light fresnel. Granted, even if I don't have that it will still be an improvement over our current situation because I can finally have properly colored specular highlights. Still, I hope that Unity, or more specifically Aras, is listening to this plea and can work something out. ;)

Alloy Skin Shader Prototype

Since I haven't posted much in a while, here is something cool I have been working on for Alloy. This is a prototype skin shader that employs all of the following:

  • Pre-Integrated SSS
  • Saturated AO
  • Two lobe specular
  • Alloy's standard BRDF + IBL

 

Check it out!
