Hello there I'm trying to make a horse model for game engine use, and I really want there to be a texture of the body fur. Given how short and sleek horse coats are, my lecturer suggested using Xgen to create fur and bake it into a normal or displacement map. I don't have much experience with xgen, so I've hit a block now…
What you need for the horse hair is an anisotropy map, which isn't easy to bake (but there might be a way with Xgen?). http://www.poopinmymouth.com/tutorials/comb-map.html
You can bake normals etc. directly from the xgen hair using Arnold RTT with one of the utility nodes (I forget the name but it's the one that can bake uvspace and world space normals etc.) You can also bake a direction map that can be used to feed an anisotropic material in the same way (there are a couple of options in…
