hope you don't mind a regular joe answering.

The simplest is to just include an environment light in the scene and you will have natural occlusion in lighting, esp with PBR and a diffuse bounce. You can separate this out for control in comp by doing a image plane of your direct/indirect/all of diffuse.

If you want a more old school B&W occ pass you can create a take in your scene. Use an environment light with no color, and all materials set to a lambert white.

Also in a separate take you can apply the occlusion shader from the material palette and not include any lights.

Thank you very very much! I got it. As your instructions, I add an envlight, and rander mode: ambient occ, higher the pixel samples and the result is good!

Thanks a billion!!!
