i like to do a lot of back and forth between photoshop and my 3d app when creating textures to see how they look on the model and having to render it everytime i want to look at the model adds another step that to me seems highly unecessary.

im sorry if my question was confusing, i tried to be as literal as possible and included the screenshot for clarity.. basicaly i want to know how to flip uv's (like in 3ds max) because the flip uv menu item doesnt seem to what i need.

as a side note this is my first maya mesh so there prolly a lot of wonky stuff going on... one thing in particular is i applied a checker to my lambert1 and had to create other lamberts for the textures because i couldnt get rid of the checker pattern.. maybe this has something to do with it?
