I am using HD RP very well. Now I can fix it myself for my usage. Sometimes, however, I wonder the intention . For example, in the case of stacklit, It write normal buffer in depth pre pass. I need two normal buffer and edge tension for skin wrinkle . It sutable for that. Am I read this GBuffer1 in stackLit's forward pass? And That hair is using unreal hair authoring teching. Make very thin hair strip and face to camera. It is very useful. HD RP' shader is realy easy and easy to modify.
