I’m trying to write a shader, that need the uv directions in different part of the texture match the flowmap direction. For example, I have a horizontal fur texture, and want to set the fur direction according to a flowmap. Any idea on the approach? Not necessary to be a flowmap though, that’s the one I can thought of that to draw the direction easier.
Thanks in advance! Tried to search for infos, and all is about how to use flowmap to make water flow T^T
