I have an asset that has a main UV map and a secondary one that is used for details. The UV map of the details is an atlas and I will have to modify it to add/remove textures. So that means I would have to unwrap again and reimport the map.
Is it possible to reimport the UV map alone?
Also, can I export a UV map to modify it in Blender and then reimport it?
PS: I know I can remove and add UV channels in UE, but I don’t want to do the unwrapping in UE since it way more difficult to manipulate than Blender and I have some addons there.
