View Full Version : UV Problem in Maya

 JGomez3d05-28-2006, 04:49 PMI am trying to unwrap an arm of a character with a cilindrical map. But is not doing what I thought it shuold. With a cylinder it lays out hte uvs flat on a plane but the arm is just stays as if it was round----pic http://img147.imageshack.us/my.php?image=cilmapping8bn.jpg http://img68.imageshack.us/my.php?image=cilmapping6ar.jpg][img]http://img68.imageshack.us/img68/88/cilmapping6ar.th.jpg

Hi, have you tried changing the angle of your cylindrical projection? Are your arms in the T-pose or at 45 degree angles? Maybe you could show a screenshot of your projection and the original geometry?

This is the projection and the uv map

You are trying to project both arms at the same time, but I think it would be better if you split the body in half down the middle, and work on only one side, then mirror later. Extract the arm so it is a separate piece of geometry, and use isolate select or hide out the other parts, then do a cylindrical projection. Click on the red thing that looks like a "T", and this will give you the same manipulator that you get for extrusions. Scale and move the projection so it fits the arm, and you will see a flatter uv layout. I hope that helps.

It looks like your problem is your cylindrical mapping tool - by default Maya only completes it by 1/2...notice that the manipulator only goes 1/2 around the imaginary cylinder around the arm. Simply grab the red handle on the corner and drag it until the cylinder wraps completely around your geometry. As it is now, its trying to map both halves of the arm with 1/2 a cylinder... it should be mapping both halves with one cylinder.

After that you are still going to have some distortion...adjust the polyprojection center x,y,z attributes...play around with them while keeping the UV texture editor window open until you get a result you can work with.

OOPS! That post you got from KrisR was typed by me...I thought I was logged in with my user account at work, but he must have forgotten to log out.
