Was given a unique challenge that might have some interesting usefulness, thought I'd bring some attention to it. The idea is more or less to use shaders and displacement to generate the crud that shows up in corners and along edges and stuff. I thought it was intriguing, but can't seem to get the regular faces clear while the spots where they join mesh up...

that does sound useful. bookmark.

Well for the same reason sss is a challenge in the P5 node system, I think a dirtmap shader would be very difficult. The main issue is that in the mat room, you build a network for a single pixel - and that pixel doesn't know about any other pixel (so it doesn't know if it's next to a pixel where the normals cross). An option would be to build a python script to run through the geometry and build a "dirt" map (as a jpg), that could then be incorporated as a map in the mat room. Another option would be to export the model to another package - back the dirtmap to a jpg, and import back into P5.
