Hi, I’m new to Unreal Engine.
I have a scene that was made in Unity, and I want to import it in UE4. Once I build the light, I get the error message that the UVs are overlapping.
Reading online I found out that until 4.6, there was a way to generate a secondary UV channel in UE4, but now is gone. Instead, the tool is SUPPOSED to generate them automatically, however, this DOES NOT HAPPEN in my case.
If I double click on my fbx, the option “Generate Lightmap UVs” is checked, but when I build the light, all the lightmaps are wrong, and I get the overlaping UVs message.
Is there something I have to click somewhere to actually force UE to generate the secondary UVs?
