Hi there.

I think this is my first post, and - go figure - it's about to a problem I'm having.

I'm currently laying out UVs for a character who's already skinned and animated, and I'm also doing the UV-layout in Wings 3D, since i consider that workflow to be more convenient. However, - and here comes the problem- when I import the .obj-file back into Maya and try to transfer the UV set from my duplicate (with the now laid out UVs), to the skinned and animated character, it simply won't work.

Now, I've read the help about Polygons-Transfer-UV Sets, and it seems pretty straightforward; select the source object, then the destination object, and press Apply. I have checked and double checked, and both my objects have the exact same number of vertices (duh, they're duplicates). They don't have the same number of UVs though, since the destination object has unedited UVs, but could that really be the issue?

I've checked the Script Editor, and this is what it had to say:

// Warning: Can't perform polyTransfer1 on disabled selection //

Now, the first thing i checked was if i had any funky selection masks or somesuch going on in the background, but I really didn't.

Could it be that I'm screwed, or am I missing something obvious?


(By the way, you may wonder why in gods name I would want to do all the skinning and animation prior to texturing, but that's basically because I had to be finished with the animation within a certain timeframe, and so the texturing recieved a low priority. The texturing still has a pretty low priority, but I really don't like when things ain't working).

uv transfer i pretty flakey i find....sometimes it works perfectly othertimes it does transfer the UVs but the somehow the uv texture was transferred....ie the uv coords are good but it doesn't match the original....bogus.

for your problem, have you simply tried exporting again.

the uvs shouldn't be the problem since it works on vertice values or whatever...i tried it out and it work with identical meshes and different UV values.

I am having a similiar problem. Copying UVs from one objecct to another. I am oing into Gnomon tonite. I will see if I can get an answer.

Anyone have an answer for this? It happens to me on occasion to. It's a real pain in the... Sometimes when I have strange problems I export my mesh as an obj and import it again. Solves alot of problems.

Hi again.

Today, when I opened my scene again, and checked my destination mesh in the UV Texture Editor, the UV set was there! Strange indeed, since it wasn't there when i saved the scene and went home yesterday.

As a precaution, I exported the mesh to .obj anyway, and opened the scene with my animated character. When I tried to transfer the UV set, it worked - just like that.

So, obviously the problem is solved, however, I'm not sure I really got the hang of what the solution was.


Thanks anyway for the tip about exporting to .obj again, I'm sure it helped.

I was having problems one time with it...can't quite remember if it was the same situation, but you may need to make sure "allowTopologyModification" is active.

You can find the check box in your components attributes under the Mesh controls there is an allow Topology Mod checkbox...make sure this is checked.

that's the only idea I can contribute.

Good luck,
DD
