create MASK features like in Mari

[zouheirito]

it is nice to have MASKS for edges and distance and backfaces like which in Mari. i believe it can push the painting inside Mudbox very far

i agree with adding more mask features. There is already a mask edges, called falloff base on Facing Angle. Whats missing is an AO masking and fractal masking.

if you can be so kind, please direct the votes here https://forums.autodesk.com/t5/mudbox-ideas/option-to-use-ao-cavity-viewport-filter-as-painting-mask... 

Thanks
