UV Area Editor
The UV Area Editor lets you cut out a piece of a texture or atlas and apply it to procedural geometry, such as a branch.
To open the UV Area Editor, load a file in the Materials Bar, then select UV Areas > Add. To edit an existing UV area, select its name. Click and drag the pivot points of the square in the preview, or enter the area numerically with the properties available.
If you instead need to create a mesh cutout for non-procedural geometry, use the Cutout Editor.
