hello im having trouble figuring this out for years in simple, what do you do, like actually make sure is added to shader code, to make your shader support basic GPU instancing, complex GPU instancing (multi-material slot matching??, texture arrays??), etc? I am trying to convert this shader to do it: https://assetstore.unity.com/packages/vfx/shaders/psxeffects-132368 because somehow THIS one supports it: https://assetstore.unity.com/packages/vfx/shaders/realtoon-an-anime-toon-shader-65518 which boggles my mind. please help!!!!!
