Best way to approach unwrapping UVWs with Meshsmooth?

Playdo

What's the best way to approach unwrapping UVWs for a model which has a Meshsmooth modifier?

MoP

Keep as few seams as possible, since they are likely to distort?

Also, unwrap UNDER the meshsmooth

Yeah...seam will be distorted...however, you can use a little trick to fix it:

Add an edit Poly Modifier between the Unwrap and the MSmooth Modifiers, select all edge and break them. Add a unwrap Modifier on top of MSmooth, open Channel Utilities and copy the Mapping Channel. Delete the edit Poly Modifier and copy the Map Channel back to the mesh.

In Headus you can specify that it will be used as a sub d and it will be fixing the seams.
Never really worked with it but its there.

one time I unwrapped my model without meshsmooth, then applied it, then dropped unwrap back onto of it, and just took a short while to manually correct the distorted edges

guess it depends on your model though as to if this will be an efficient solution or not, it was for me at the time

You could try unwrapping in a tool like modo that respects smoothing on the UVs, and just export the sub-divided version back to max. This would result in a pretty dense mesh, but might be ok depending on what you need uvs for..... Why do you need uvs on your sub-d mesh, anyway?

+1 for headus uvlayout.. unwrap as a subd shape and forget about the problem.
