This thread over on polycount goexs into the flow maps How to paint flow/anisotropic/comb maps in Photoshop. — polycount.
Veretex paint for direction isn’t really an option for me, it’s not fine enough. I hadn’t noticed you support normal maps and vector maps for brush direction, probably overkill to add another map functionality.
Do you have an example for a vector or normal map driving the fur direction? I’m not entirely sure what a vector map is, is it a vector displacement map?
There is no fur base material. There is a broken fur material function though.
I tried cleaning everything up but there is no difference in the download. I allready did once befor based on the comments on the markplace page. The source on epic’s servers is broken. Try to re-upload. maybe you also need to increase the version number so that peoples launchers realize the source is updated.
