Regression
Yes
Assertion '(srcInfo.GetChannelMask() & copyChannels)==copyChannels' after marking mesh without lightmaps UVs as lightmap static
Steps to repro:
1. Open attached project and 't1' scene;
2. Drag prefab 'Cube_3-materials' (having no lightmap UVs) from the Project folder to the Hierarchy;
3. In the Inspector mark 'Cube_3-materials' gameobject as 'Static'.
Actual result:
Assertion '(srcInfo.GetChannelMask() & copyChannels)==copyChannels' is thrown. See attached video.
Regression introduced in Unity 2018.1.0a1.
Expected result:
No assertion are thrown after marking gameobject with mesh having no lightmap UVs as static.

- Not reproducible in 2017.4.1f1, 2017.2.2p4 .
- Reproducible only for mesh having no lightmap UVs; not reprorducible if lightmap UVs have been generated automatically for the mesh.

I'm facing this issue, worked around using 'Auto Generate Lightmaps UV' in the import settings, But I'm facing NavMesh causing Unity to crash when trying to Bake the models. Do the two bugs relate?
