Yes the correct way would have been to make it modular. I would try using UE4s import options to generate lightmap uvs and if that didn't work then I would either break it apart and make it modular or only use realtime lighting. It is not going to be worth it to set up lightmap uvs like this manually.
Aren't those meshes modular? doesn't that mean that the best way to approach it, is to just Lightmap one of the Tiles? Gives it more space in the UVW, which should be better overall? I maybe wrong! =)
Hi guys, we start texturing most of the building. -- for light mapping how the best way to prepare it ? since the building is attache and not modular. I am doing like this : is it a correct way ? need helps for light map. thanks
