Combine Meshes without Overlapping UV's
Ok, so I have a Fridge that I've modeled in Cinema, each element is broken apart such as Door, Chrome Handles and so forth. I've got those meshes grouped under a null a 0 point and each mesh has two sets of UV's. The problem is that if I wanted to bring this in as static combined mesh all of the UV's stack over each other and cause the light map to fail.
If I don't combine these meshes everything work's fine. I would assume that my UV's might have to respect each other in their placement, so when combined they merge correctly. But I was wondering if there was a way to avoid this type of work.
Thanks in advance.

You go it! That's exactly what you would need to do. If these meshes are combined within UE4 on import and the UVs are not laid out in a way that they will not overlap each other this will cause the overlapping issue you indicated.
If you're going to combine you need to make sure they respect each others bounds by having their own unique spacing to avoid the overlap since their individual UVs will be combined into one once they are combined with the import.
If you have any other questions about it or need further clarification let me know, but it seems like you've already got a good understanding of how they affect each other. :)
