Alright, here is the issue I am having. On the left are the uvs as they are in Maya, and on the right is what they end up as when importing into UDK. Has anyone run into this issue before?
are you importing via FBX? Make sure you trash your history and freeze transforms before you export. FBX has a nasty habit of remembering that stuff :P
Also as a side note -- you might want to sew that stuff up. Unsewn UVs are going to give you nasty seams and add to your vert count.
Yeah, using FBX. I definitely deleted history and froze transforms. Even tried combining the mesh to a cube, deleting the cube, and importing in to UDK again, of course deleting history and freezing transforms as well.
It's for a vegetation object, so that's why nothing is sewn. Very strange issue though, could the UV's be screwing up upon import into UDK? Weird stuff, hope I can figure it out somehow.
Ah, gotcha. Yeah UDK can scramble UVs if you are importing multiple meshes and let UDK combine them. Is each leaf a different mesh? If so, try combining them first.
I made sure to combine using the standard combine option in maya before I exported. I do keep them separate when working on them, but then combine them for export.
Just figured I would update this thread saying how I fixed it: I had to use the uv set editor to create a new uv set, the problem seemed to be with the create new uv set toolbox.
so the end result was a static mesh with 2 UV sets, and that fixed it? oh UDK, you so silly. glad it got fixed! I would have never thought to do that -- I routinely bring meshes in with only 1 set.
Yeah, it was sort of on a whim; I just search about how to create lightmap uvs in Maya to bring into UDK. Since the tutorial specified to use the uv set editor to create the second uv set instead of the 'create new uv set' toolbox, I gave that a try and that worked.
