Any tools for a few specific kinds of bakes?

There are a few kinds of info I’d like baked into textures, that shouldn’t be hard to get, but that I can’t get with Blender nodes.

  1. Distance from seam. World space, UV space, whatever, just some kind of distance from seam would be nice for modulating detail bump maps.

  2. Texture stretch. Basically, just delta world position divided by delta UV. For limiting detail bump or modulating clothing transparency.

Anybody know about any tools/ addons that can get me these bakes easily?
