Just received a newsletter from the company confirming 3DC's PBR implementation, although they didn't elaborate. However, the screenshots they provided were in the Paint Room, not the Render Room, which is interesting as I assumed it would somehow change the way things are rendered, not actually implemented. It makes me wonder what is actually being changed in the typical 3d process. Is there something in the mesh itself that's changing, something in the maps, or is something new being added? This might be an exciting development.
