This was fun to do. The wicker pattern was derived from the same techniques used to do the Canvas substance. Since the wicker pattern is lower frequency, you can dial in a greater amount of detail. For patterns like this, it’s super vital that you have a tile generator/random on the side that can do color randomness so you can later directionally warp the albedo map, making it look more 3d. This was my reference:
Getting the shades of brown wasn’t too tough, but mixing in that purple proved to be challenging. Most of it was done via blending two ambient occlusion maps of different spreads, then mixing in some quick dirt blends.
Of course, this looks much better with parallax. Marmoset Preview doesn’t allow for it unfortunately.
