use the reaction diffusion node for that top bit - its perfect for it unless it doesn't exist in painter - in which case make a painter tool using designer
I baked fibermesh on a plane to get normal and diffuse ... it worked but it didnt look that good from a distance .. any way to improve it or any other way to do this ??
There is my test model of old church bench, 603 polys. Diffuse, normal and specular maps (each 1024). Reference photo by 3dmotive's Don Ott. Thanks everyone for feedback.
