Just purchased this shader.
About the brush direction, I see that we can adjust the direction of fiber flow using the RGB channels. I’m not sure I understand how that works exactly, but easily enough I can play with the settings in a material instance to get results. But, lets say I want certain parts of a models fur to flow one way or another. I need a texture map to drive that behavior, but I don’t know where to start with that. Would it be something like, separate the model into RGB colors, and each RGB value I can then control separately? So an animals legs I make red, its torso I make blue (just a simplified example), and then in engine I can adjust those values to get the right flow?
