Hi Clockwork, Thanks for the reply,
I guess my understanding of lightmaps is wrong. But how come that if a shadow is baked perfectly over 2 models I still see a seam when two models are close to each other?
In addition, when I see walls made of modular pieces or just large geo’s I don’t see any lightmap seams when two pieces are adjacent with each other. As far as I know ground, floors and walls are not one big piece of geo. But cut in several pieces. For example, the ground outside, let say a forest, road or street. Guess I’m missing something? Hopefully you have an opinion on this.
The seams of the ground are fixed at this moment. I’ve copied uvset2 to uvset 1. So for some reason UE4 still chose the previous version of uvset 1 even though I set it to use uveset 2 for the lightmaps.
