UV Unwrap retopo objects individually??

[Beddall]

Hey,

Is it possible to 'Unwrap' retopo objects individually when they live in the same scene?

I have 2 retopo objects ... A + B..  

I have already unwrapped A, and edited UV's individually to get the exact layout i need. 

I import Mesh B as another retopo object as it's the 2nd half of mesh A.

I try to unwrap it but whenever I do this it unwraps both models, overwriting the changes I have already made to mesh A 

The meshes live on seperate layers in the 'retopo objects' window. 

I've tried a number of options but I can't seem to find the workflow for unwrapping just the one mesh. 

any help would be greatly appreciated. 

 

cheers

If every model have their own UVset, you need to create a new one by mesh.

HI, 

unfortunately they don't have seperate UV sets. they need to be paged up onto the same texture page. So i need to be able to see all UV's at the same time, but only unwrap mesh B. 

I think i have found a solution by using 'To LSCM' in the selected section.  it was having issues i think because, 'select UV Shell' selects uv shells based on their position in UV space it seems.... not based on whether or not they are actually connected. So I had marked all my seams... updated islands... but it was still selecting the whole thing as one UV shell.... until i moved them apart manually, face by face in the UV preview window. 

Thanks for the help

your workflow is correct.
