I've been using Photoshop proper for quite a while, but have just recently started working with the 3d aspect.

I have some tileable 2d images as source (human skin) and some importable 3d models with uv maps (human body). What i want to do is paint the 2d onto the 3d but not in a 1:1 size ratio. If I just plonk a texture in as a diffuse, it covers the whole body with one iteration of the texture.

My experience with photoshop says that I need to create a material > diffuse using my source 2d image(s) tiled however many times and brush it on as needed. If at some point I need to scale the material, then I'd need to basically remake the source 2d.

This however seems old-school, and google is happy to show me results for painting solid colors (not what I need). Is there a better way using current features? If there were a tutorial somewhere out on the web, I'd be happy to see it.
