CGTalk - Help on UV Layout

Hi there guys, I'm just a rookie here in Maya, but I've been working on it for a couple of months. Now I'm stuck.

I created a creature on polygons. I rigged it so that I could make a walking cycle, and textured laying out every part on the UV Texture Editor.

Everything seems to work fine until I start animating, once I move any bone, all my UV's get screwed and the texturing layout is completely moved.

Is there anyone that know what is going on ?

Thanks a lot

Cheers !:beer:

I had the exact same problem! This is what I've been told. You could try 'convert to file texture' That's in the Hypershade under the edit pull down menu. That's suppose to work. (But it didn't for me)

Here's what I did (It's kinda wierd though). I duplicated my polygon. then transfered UV's to the new polygon. Under 'Polygons - Transfer - options' then choose UV sets. Then I transfered it back to the original model and the textures "stick" to the model now. (Oh by the way I'm a beginner too so if anyone knows why this is happening... I'd love to hear your thoughts.)

Hope it helps

Could be one of may things:
1.) make sure you delete the history on the model after putting all the uvs on it.
2.) Make sure your texturing it with the uv's and not a shader projection.(when you add an image to the color channel make sure you pick "Normal" and not "Projection" when picking "image file" or a procedural texture).
3.) When you create the uv's(edit polys > texture > planar/spherical/cylindrical projection) there is an check box called "place projection before transforms" or something like that. Make sure it is checked.

Also: A bug that I don't beleive was ever fixed within maya, sometimes an objects uv's get horrifically messed up with no way of retreiving them. A work-around for this is to delete history on your final model (if nessesary), and then do a polygons>>Move component. Grab a few UVs in the UVeditor and move them slighlty. This will create a polytweak node in the Objects history, thus preserving the objects UV's. I know its a pain in the ass, but I do it to ALL my models.

Ive had a few UV'de objects explode on me.

Hope this saves some people a LOT of trouble.

Hahaha... I knew something was wrong! :) It took me a few days to figure it out, cause I figured it was something I was doing wrong. Wish I found that out sooner, thanks for sharing that info:beer:
