I'm not exactly there yet, I'm struggling with intermediary math, I solved it mostly 'visually', but I don't see any obstacle to implementation except my might skills. The idea was to raycast in shader using wrapping function to get the parallax of hair in a single hit, and get potentially the exit accumulation of all hair in a single compute. Last time I said I might have made a breakthrough for curly hair shader, I have laid out some prepatory work, I'll share in case people are interested. will be happy to get help and make it work. right now the collision of the system is broken from my tests. anything that is not a new sphere will not work. Tried to match the FBX human to my fbx sphere entire settings but still not working.I go back to maya try to reset all the human attributes maybe it will work. ill import an fbx clean sphere and will try again.

My model is simple fbx human girl no bones no animations no morphs. None of the hairs seems to respond to the collider when i press play and moving the object with the move toolĭid exactly the same test on a unity sphere and it is working. I added the 2 colliders to the collider list under the motion tab, Using the collider tools i place it where my long hairs are.
