What i mean is this. The original UVs are overlapped, so my 3d artist exported the same fbx with another set of UVs that don't overlap (the overlapping ones are still there). so i thought that i could map the atlas based on the same original textures but using the second set of UVs (since the first ones overlap). I have already checked in the source files (although js is not my favourite) and found a function called ModifyUv (line 489 of BatchingTools.js) and i figured out that if the is something that can be done it could be done in here. is all this possible? The tool actually works great, but i overlooked the "non overlapping UV" thing. I really need to get this working without forcing my 3D guys to remake all the textures.
