#1- How do you verify if it is actually working?
Following the most simple example, the material stats / platform says the Texture Lookups Est is still on Pixel Shader PS rather than the VS. Are the stats correct?
#2- how many on ES3.1? That is a main use for many yet it isn’t specified
“Shader Model 5 on PC can use 8 custom UVs, while OpenGL ES2 on mobile can only use 3.”
Trying to get it to work with Bump Offset, but I honestly cant tell if it is performing an optimization or not
