Hello, I passed from Max 8 to Max 2010. And something really usefull is missing now. Into Max 8 when you were selecting fews polys in EditablePoly than switch to UnwrapUvw modifier. 3DMax kept in mind the selection (That was perfect because Editable Poly do have better selection tool than UnwrapUvw) more off all sometime…
works for me, even the other way around: select some faces in UVunwrap mode and then apply a editPoly modifier: it keeps the face selection. I use this quite often to delete unnoticed and not needed faces during the unwrapping process.
if you select your faces in epoly and leave sub object mode without deselecting anything, then apply the unwrap mod. When you open the unwrap window you might have to go to faces mode to see the faces selected.
Actually my solution is different than what Vig wrote. Vig said to not deselect things and add the unwrap modifier, he didn't specify to leave epoly subobject mode and then apply the unwrap modifier. He said don't do 2. That's all he said. I did specify what to do because you get different results depending on how you do…
If we do like you're saying Vig, inside the Unwrap UVW modifier your selection is stucked. You cannot continue unwraping other polys without re adding an other Edit poly/Unwrap uvw modifier or without collapsing your stack and adding an other unwrap uvw modifier.
