Atlas UV Editor

Sometimes you may wish to cut out a piece of a texture, perhaps from an atlas, and use it on something on the tree. This is different from using a mesh cutout in that this texture area may be used with something that generates its own new geometry, like a branch. This piece of an atlas may wrap seamlessly already, even though it is in an atlas, so it could be used on a branch with no problems.

The area may be edited by clicking and dragging the corner points of the square in the preview, or you can enter it numerically with the properties available.
