well, obviously nobody can help me with that UV transfer.
however i figured out that something might be wrong with the polygon geometry in the first place...

i tried to convert it back to a polygon object and for some reason the edges (in object mode) are dashed, as somehow 2 edges are in the same place.
when i pick some vertices and try to move them, something odd happens: the vertices seem to double, and i can only move what appeards to be some kind of hull but the shaded geometry itself won't change. WTH????
i added 2 pics, the first one is to show the edges, the second one to demonstrate the "doubled" vertices of whose i moved a few...

of course i tried to cleanup nonmanifold geometry, but nothing happened.

PLZ, that's not the first time this happens. the has to be a possibiliy to make this unhappen...

by the way... i upgraded to maya 2010 and same problem here!

alright, problem solved

once again i found the problem. for any one who's interested:
i converted the sub-d geometry while still beeing in poly proxy mode.
converting from standard mode won't damage anything.

i just can't understand why maya doesn't warn me... maybe it's what we in germany call SCHADENFREUDE-
solong---

still got the uv transfer problem... isn't der any nerd who can solve this mystery?? :-)

Maybe try converting it bad to Sub-D and switching to standard mode, then converting back...
That works for me most of the time.

UV Transfer

yeah, i figured that out, too. i don't have that corrupt geometry problem anymore.
either way, my UV transfer crashes.

but i found something out:

i made a copy of my sub-d model and modified it to map the UVs. i also did "average vertices" and remodeled the legs to get primitive geometry (like cylinders) for mapping.

when i do average vertices on my original model as well (just for a test), at least the UVs of the head are transferred correctly.

i don't get it: in this tutorial, they said you can transform the geometry (that is, its copy) as long as you don't change the number of vertices, and that's exactly what the do the whole time...
i got the feeling, the transferred UVs are only correct, where the copied model is exactly the same as the original.

can somebody confirm this or correct me? is there any secret option box like "keep UVs in world/local space"?
