hi

i have made a model 'A' in 3dsMAX9 without any UVW mapping to it

and
1. Rigged and posed it , and saved it as 'B'
2. made UVW mapping for it(without rig or posing) and saved it as 'C'

im sure that was pretty stupid thing to do, but lets move on to 'the question'

1.how do i export my UVs to the rigged model? (it has the same number of polys/vertices....its the same model)

2. if thats not possible, then how can i make my uv mapped model, get posed/morphed into the pose of the rigged model? ( for now i dont need to have any rig, i only need the POSE)

thanks,
Vamsee

I would try the following:

Apply a UV Unwrap modifier to C and copy/paste it to B.

You could also try Skin Wrapping B with C or try to copy the skin/physique information from C to B.

Yep the above motioned works

You can also save the uv mapping to a file in the UV unwrap window menu.
Then put the unwrap modifier on the rigged model then open the save uv on the rigged model.

That should work, since they are the same models. I think I've done it before....

GOOD LUCK !

yup u r right ......... thanks

but it did not work for me, coz i have some more polys to the model while posing, so it was not working for me earlier .......

i think i can fix the problem now, thanks all

I don't know about Max, but Maya has a 'Transfer Attributes' tool for pollies. Makes it easy to transfer UV's from 1 model to another. I'm assuming Max doesn't have anything like that though. I'm sure if it did someone would've mentioned it. Right?

i dont know either ........ i havent seen any such 'attribute transfer' in max
but u sure can import the uvs, as long as the model remains same.... i mean no new polys added or deleted .......

Yeah, I'm not sure if it was completely necessary in my case or not, but I just added a couple edge loops and merged a few verts on the UV'ed model to make it match the rigged one. It's ok if the rigged model changed a little, as long as you can make the changes in the UV'ed model so they more or less match and have the same vertex count.

is it? ........

sounds very appealing ............. may be i shud start learning maya .... somehow
