I watched the recent 4.7 video, very cool stuff, one question does this software support painting of displacement maps while on PBR painting, I ask this because with the release of Quixel Megascans I would be glad to paint everything and get color, normal, and displacement to match perfectly. If this is not possible at the moment, a tweak to add a temporary additional channel to the smart material layer structure could help too, maybe with a preview of just the channel painted layer and not the deformation achieved that can anyway in part be previewed by the normal maps. Though I think 3D Coat should definitely fully support displacement maps in PBR painting mode(with Catmull Clark/Open Subdiv subdivision pattern).
Not all people work on low poly assets, and 3dCoat could easily lead the change on this. I think many would appreciate this feature expecially after the Quixel Megascans official release. Thanks for the attention.
