How to auto-generate UV Lightmap?
Hi, I have a static mesh. I added in blender a 2nd UV Texture. Now I have 3 UV Channels in my Static Mesh (no idea why). Well, I can't seem to find the option for auto-generating uv lightmap. It should be in the window drop-down menu but it isn't there.

If you have more than one UV map in your FBX export, UE4 assumes the first UV map is the texturing data and the second UV map is the lightmap. If it's not a second channel in the FBX, UE4 will ask you if you want it to generate the light map on your own at the time of import. I don't think you can ask it to build them later on without a reimport. Although a lot of times it doesn't do the greatest job in the world for light maps and people make their own.
