Needed something that adds a more dull and used look to stuff. The main thing is not so much the rubber/latex surface but the grungy texture. Depending on the color, latex or rubber is a good base to show how different stuff like dust, oil, weather, age etc. can affect a surface. Training was done with a lot of imperfect surface textures and of course latex and rubber stuff, all generated in SD, so no real photos.
Indent to use it maybe at a lower strength to give some things a bit of a more dirty look, instead of the clean stuff AI produces all the time. Of course, can also be used to just turn something into rubber or coat it in latex.
