I read the instructions on the Quixel Wiki page and it says that the curvature/cavity map is the most important input. I understand but to my understanding cavity and curvature are different things.
Cavity is a grayscale map but curvature can be a red and green map showing the convex and concave surface.
None of the sample projects contain cavity / curvature so I couldn't check it out by mayself.
Which one do I have to use?
Thanks for your help.
