I wondered how to keep two UV separate UV maps when merging two objects into one (CRTL+J)? Currently I have blender 2.80.
I have two separate objects (in this case a turtle and a catapult from a game). I would like to merge them both and let each keep it's own UV map. In blender this seems alright before merging. However, after merging they are converted into 1 wrong UV map. The turtle's UV map is degraded into a single pixel in the lower left of the UV map, resulting in a mono-colored animal. The catapult has it's texture from in game, so I cannot supply it (but you can see it in the object).
