Maya UV Editor problem

brendanfitrider · Dec 2016

Hey, I have a problem sometimes when I open a project I have been working on in Maya 2016, where the UVs go from neatly packed in the 0,1 space to scattered all over the place like in the picture below. I can't figure out how to revert it back to the way it was, and it tends go back to scattered after I repack it all, save and reopen again too.
Is there someway to fix it? Or just a way to avoid the problem entirely?
Cheers

Have the uvs been unwrapped already, and it scatters about later?

Yeah it happens after I've unwrapped. This particular project I had already packed it all neatly as well. As far as I can tell it just happens randomly sometimes.

Do you delete the history after packing and before saving?

I've seen UVs behave strangely when working on models or with tools that don't generate construction history. Performing an undo will sometimes irreversibly revert my UVs to some past state and there's no way for me to recover (seemingly at times where the first construction history state appears and it is undone). Try giving it some construction history for the UV mapping nodes to rest on top of. Something simple like a Transform Component with no change in the values. Probably a long shot but it's a possibility.
