Yes, for the adventurer outfit I put the UVs for each item into a separate tile so I could see the layout better. Poser has been able to handle that since I can remember, as is pretty much any modern 3d software. If I remember correctly, there's a setting in the texture map node, which should be set to tiled. Will check after work.

Normally, I develop each clothing item separately, so everything's in the default tile.

ETA: if the multiple tiles are a problem to some, I can try to remember not to do that in future items.
