Case 2.
my aiStandardSurface1 not connection other node Case 1 and Case 2 is same aiStandardSurface setting
So my question is, why aiMIxShader incerase more render time? And How to optimiza aiMixShader? Cheers, Sum
My understanding is it would be running each shader separately and combining the results, so it makes sense it would double render time. What you can do instead is use the mix shader on inputs to a single standard surface, such as mixing the diffuse texture from several input sources before plugging them in.
