Copy Uv Set From One Object To Another

[joojaa]

i must admit according to the manual im exploiting some bug here.... wich is bad for productional operation. So i wouldn realy rely on this it seemed so good when i was tired yesterday.

Well using API

MFnMesh:: getUV
MFnMesh:: getAssignedUVs
MFnMesh:: clearUVs
MFnMesh:: assignUVs
MFnMesh:: setSomeUVs

Should be quite straightfoward ill look into it but im realy busy here im having 4 deadlines on monday!

No matter how i try to follow the way u did it, it doesn't work. I've tried every combination of what u mention. and everytime, the target cube gets its UVs overwritten. it doesn't matter how many copies of the uvSets I make, or weather they are empty or full.

Please simply post your simple working scene with the cubes setup to easily copy UVs, demonstrating how its possible to copy isolated uv sets. Then we can all have this question answered once and for all. If its all setup as you have mentioned, we should be able to transfer UVs and see for ourselves the proper way to set it up.

looking forward to seeing your working scene.

I have traecked the porblem. Yes i know why it sometimes works for me but not for anybody else. is a bug in my on work data universtalisation code.

well thing is i can do it withiout undo bot implemeting undo for the universal traslator is NASTY... besides i dont on purpose realease api code. Yes alias can fix brobably with far less code i would need.

BUt i cantrealy relese exprerimental code, and i dont like to workin the api for free. Because its TRuly work... Mel one can usualy whip up in 5 miinutes but in api soetimes even simple stuff takes days to do.

//select the object you want to get the uvSet from then add select the object you want to add the uvset to..
copyUv(ls -sl -fl, "newUVset")
