Hello. I am interested in getting started with selling 3d models in the Unreal store. However, I read that one of the requirements for models is that they cant have overlapping uv’s so lightmaps behave correctly.
Its not too hard to uv map a model with non overlapping uv’s, but some parts of a mesh (like many small details) can take up alot of the uv space and would be best suited overlapping each other. An example is railings on a staircase.
What if the railings was part of a bigger object like a ship and you wanted to keep everything as one texture or material? How would you fit so much on a uv map without overlapping uv’s while keeping the resolution acceptable?
I don’t have any experience with lightmaps or Unreal yet, so all of this is new to me.
