Symmetry On UV Maps

[womanonfire]

hmmm... in my experience, if you cut a model in half and mirror it, it also mirrors the UVs meaning that when you sew the model back together again, the UVs of each side are on top of each other. In essence they are now mirrored symmetrically just like the model is. but maybe i misunderstand your question?

yep!Thats what am asking.So its possible that we edit uvs of only one half.Still not sure??Someone please clear the confusion.I always collapse the geometery(symmetry) before making UVs.

I take it you are using Max? What you do is, you overlap the UV's from half the body to fit the texture map.

A. I can't remember exactly how it works in Max, (if I'm wrong about Max, please someone correct me) but you should be able to map the UV's on half the body, then mirror/symmetry the other half of the body. You should then have the correct UV-map on both sides.

B. Another way of doing it would be to do like you usually do, collapse first and then map your UV's. The downside to that, is unless the two sides are different in some place, then that would give you twice as much work as you would work on both sides.

After mapping both sides, then take half of your map and mirror it and overlap it in the texture editor.

The A-alternative is an easier and quicker one than B. I haven't worked with a later version of Max than 5, so a lot of things might have changed.

Someone else might have a better solution for you.

Am using both max 7 and 8.After applying Uv modifier on half body(with symmetry) when i'll edit the uv manually will i be able to move the vertex of both the halves simultaneously??Since the two will be overlapping each other.

I don't have or use Max 7 and 8, so I am not really sure about this.

You should be able to move both vertices from both halves at the same time, but to do that for a whole character, I don't think that would be very efficient, it sounds quite cumbersome.

If both halves are identical, I would only work on one half and then mirror (or symmetry) the half body that you have UV-mapped. You should get the same UV-mapping on the mirrored half. But why dont you make a quick test on a sphere or box with some polys and see what happens and how to best solve it.

Maybe someone else can give you a better answer.

Sorry I can't be of any more help.
