Abyssal Void (Unlit Unity Shader)

About:

The Abyssal Void Shader was originally designed as a means of allowing a pitch black body to be seen over itself by adding a slight, almost imperceptible violet edge glow.

I made it for my purchased copy of Sillurgy's "Abyssal Rapace V3" (awesome model, by the way), but through later experimentation, it was discovered that this shader works quite well on really any matte black avatars, and can really create a unique look and feel for a general "void avatar" style. As a result, I have chosen to release this for free!

The shader is intended to be dark and difficult to see. You can partly customize this, such as by changing the glow color or the sharpness of that glow. It's a bit like rim lighting, but it uses the normals of the model instead of per-pixel colors, so it won't be a cartoony line like you might have come to expect from other shaders.

Performance Implications and Features:

  • This shader is computationally cheap; you can generally use it extensively at no cost.
  • [VRChat] The shader properly tells VRC to fall back to an unlit texture, so if your texture is mostly black, it will still look decent.
  • Shader properly ignores projectors and lights, and does not cast a shadow.

Limits:

This shader works great when:

  • The avatar has no large areas of bright color that may cause the focus of the viewer to change
  • The avatar is as dark as possible
  • The avatar has sharp angles over a short distance; less large, flat surfaces.

This shader struggles when:

  • The avatar has a lot of bright colors
  • The world ambient color is not a color that provides contrast to the dark violet tones
  • The shader is applied to a texture with colors brighter than pitch black (#000000) - the violet applies additively, and so it will be drowned out by other colors.
