Currently working on a landscape material that I would to take advantage of Bump Offset/Parallax Mapping.
My basic setup - https://i.gyazo.com/2bde3a2e93cccbdb7b78421a4b0fef64.png
Q1 - Is there a reason why we need to plug in the output into all the texture UV’s? In theory will I notice any performance gains (no matter how small) just hooking it up to my base color and using regular UVs for the others? (Early tests show no difference, but I’m going off of FPS which ofc varies)
Q2 - Lerping between Bump Offset and regular UV’s based on pixel/camera depth seems to give me big performance increase, is this just a case of shoddy profiling or is it actually doing something useful?
