Transfer UV between meshes

[Anonymous]

Hi,

I am trying to transfer UV's between two meshes with the identical poly count. one mesh is an open hand and one mesh is posed as a closed hand. 

I need to transfer the UV's from the open hand to the closed hand. I tried the projection method but it doesnt work. I even tried saving the UV's into a file and loading them up on the target mesh but that didn't work either.

Any ideas on how I might transfer UV's the two meshes? 

Thank!

Hi,

The problem is that you're trying to copy UVs on two objects with different topology,

That will result in distortions inside the texture, specifically where the two differ from each other,

And you cannot avoid that.

When you mentioned that it didn't work using all of these methods you tried, did you mean these kind of distortions or something else?

Thanks for replying. 

I meant that I am getting all kinds of distortions on two geo's with the same poly count. Their topology is the same and the only difference is between the poses. 

I have a character in max which is CAT rigged and I took the geo in Maya to re-uv it. Now I want to transfer those UV's to my character in Max so that I can texture/shade/render it.

I used topology in the wrong place, i meant the distortion between the polygons where they differ,

Topology is the mesh internal structure,

Anyway, i'm afraid you need to unwrap it in Max, there is no quick / one click solution for that,

I was thinking of using the Morph modifier on a copy of the opened hand and use the closed hand as a target,

This way the open hand will morph to resemble the closed one at the last frame of the time line,

But this will create distortions in the texture where both objects differ from each other, while maintaining the integrity

of the mapping where they stay the same.

I don't believe this is what you want anyway.

You're right. The vert order is changing so its not going to work. Ah! I guess I get to do my unwrapping in Max. thanks for the replies! 🙂
