I always do Cavity and Convexity maps with BakeMaster's Curvature map by modifying the default values. Its default Cavity map is based on the Pointiness of the object, whereas it is expected to output results similar to if I were to bake an AO map with a tiny distance value.

Describe the solution you'd like to be implemented

1. Rework Cavity map to include a toggle: switch between Blender's Pointiness look and standard (like AO map with little ray distance).
2. Add Convexity map to avoid manipulating Curvature map to achieve that map's look.
