I am creating this brass table with glass shelving model for a game. To avoid breaking things, I can only have one mesh for the table frame and one for the glass shelves. I currently have a bunch of rounded rectangles for the frame and three flattened cubes for the shelves. The frame with legs is one object/mesh and the 3 shelves are another. I also need the whole table frame on one UV map layout and the glass on a separate one.
I tried joining all the rectangles for the frame and just doing Unwrap and it seemed to work but then all four legs were not mapped. So the only other solution I could think was to map each object separate and then join it all together after. Is there any way to do this where they'll be all on one layout? I was looking at the multi object uv edit add-on and it looks perfect but I really need to join everything in the end to what I described so not sure if that's going to screw it up.
