ForwardAdd pass

Ok I'm trying to make one shader that does lit and unlit ( changed via options )

is there anyway to keep a shader from calling the ForwardAdd pass if the shader is unlit when a pixel light is in range ?

 

It might be possible to use SetShaderPassEnabled to do this. While the documentation isn't great, you should be able to do this:

material.SetShaderPassEnabled("ForwardAdd", false);

https://docs.unity3d.com/ScriptReference/Material.SetShaderPassEnabled.html

The preview Standard Particle Shader uses this to enable/disable an "Always" pass it uses for distortion.

I will try that ... that did not show up in my docs earlier today I must have been looking at old version

thanks !
