Does anyone have a good suggestion on how to properly apply the scale/chainmail texture to Captain America’s shirt? I want to do the comic style ‘scallop’ pattern…
Instead of a textural solution, you could also opt for a geometric one with nanomesh, which provides convincing results if you’re willing to experiment a bit. I did this with basically no effort on the demo soldier model with basic circular nanos:

The key is to make sure your target polygons are as evenly shaped and distributed as possible, so you’ll want to duplicate your tool and use Zremesher on the duplicate with a lowish target polycount and a low AdapativeSize setting to get as square and even polygons as possible. You’ll also find it helpful to divide the mesh into different armor section polygroups, rather than apply the same nano settings to the entire body globally. From there experimenting with different alignment settings, nano shape, and axis rotation should get you the results you want with a bit of tweaking on problem areas. Delete the remeshed target geometry when finished, and tweak lightly to make sure it conforms to your high poly mesh.
Good luck!
