How to bake a Curvature Mask into a Vertex Color Channel?

I am referring to this video below, released by Epic. In which was explained, that AO, Curvature and Thickness was baked as vertex color information into the separate RGB Channels.

Nanite in UE5: The End of Polycounts? | Unreal Engine

How the heck can we do this within Zbrush?

Thank you sooo much for any little help,
happy pixeling

This would require you to understand Polypaint in ZBrush, as well as the some of the advanced options in the Masking menu. If you can mask your mesh in the proper way you can apply color in specific ways to your mesh, then export that color information as a texture.

In the specific case of Curvature maps, this usually involves Cavity maps in ZBrush. A quick search turns up a number of available online tutorials on this subject.
