2- A [Transform UV] tool, to scale/translate all UV coordrinates.
Useful for when you unify textures in one sheet
Point 2 The UV transform tool is similar to the XYZ roto-translate-transform tool, but works with UV coordiantes (and it lacks rotations, because I'm lazy and I didn't need them). This is useful, for example, when you put two or more sheet of texture together. All the meshes using it must adapt to use 1/4 of the texture space, and this is what this tool does for you (as usual, bulk edits are possible).
It's fully interactive, meaning that you preview the results while you do it, and can cancel if you skcrew up.
Another use is when the texture is flipped in the vertical direction (this happens all the times). The tool has a preset to flip it back (scales the V by -100% and transaltes it by 1, meaning that it flips it).
