Files in the first two scenes (synthetic_mat_1 and synthetic-mat_2) have two layers, they may be mixed with each other through a alpha (transparency) map.

For example add stitch texture to the plane , then use shrinkwrap modifier array modifier and curve modifier for placing stitches on the model. Textures can be easily converted to other formats in Photoshop etc. Tested also in Cinema4d and textures working very fine.

I have added a preview images for each .blend file to the main folder for better searching.
