Import FBX, doesnt auto-generate lightmap for one mesh
Build: This is a binary build, Version: 4.10.1-2791327+++depot+UE4-Releases+4.10
Details: When I import a single FBX (but with several meshes). I don't combine the meshes, and UE4 won't autogenerate a lightmap for the final mesh that it imports. It generates lightmaps for the other meshes, except for the last one.

Repro Steps: 1. Import an FBX 2. Select 'yes' to autogenerate lightmaps 3. Select 'no' to 'combine meshes' 4. Select 'import all' and let the meshes, textures and materials import 5. Check the number of UV channels... the last mesh will only have one UV channel because a lightmap hasn't been generated for it
Additional: This issue seems to occur 100% of the time. I'm using Windows 10 on a fairly high-spec MSI gaming laptop..

Using your repro steps I'm not able to get the same result you've described. I've only made a simple asset that has three differently shaped boxes. I've tested in 4.9, 4.10, and 4.11 p3, without issue.
If you'd like to attach a test asset that this happens with, in a zip file I can have a look and see if I can see anything out of the ordinary.
