What's up guys. Had a quick question on Cavity Maps. I currently use cavity maps to make my spec map pop out more, but is it useful to use cavity maps on top of diffuse, say overlay or screen blending mode? I've done some tests and can't find the right blending mode on which to set the cavity over the diffuse, but I've herd it can come in handy when making the diffuse details pop out more. Any ideas?

In a very general sense, cavities contribute a very subtle amount of detail to the diffuse, but this can vary wildly.
Make it look good in your eyes.
Anyway, for things like rocks I usually put a bit of cavity map on top overlayed but with an opacity of like 10% or so, so you can just slightly see it.
