Hello, i have this issue with the light mapping on my meshes. I have this building consisting of many pieces, that imported as one fbx. The reason for this was so i could use the substance painter link in UE4, for the great convenience and time saver that provides. When i look at the mesh inside the editor, i can see that all the meshes are separated, with each their own uv set, however the lightmap has generated and collected the entire building on one uv set, which of course removes the option to control the density etc for each asset.
So my question is if anyone knows if i can generate new light maps for each asset somehow?
Hope someone can help!
