A cavity map is a texture that stores small-scale ambient occlusion. Also called a Crevice map.

Cavity map is different from Curvature map which stores the convexity/concavity of a mesh.

To bake a cavity map, use ambient occlusion with the ray distance set to a lower value.

Cavity maps use the same baking method as ambient occlusion, except it captures smaller details. Images by Marmoset.
