BSP Converted to Mesh is black

Hi!

Could you show us the lightmap uvs of those black meshes?

I’ve converted few BSP brushes into Meshes and they appear completely black.
They appear okay as expected in model viewer but when in level - they are completely pitch black.

Other non converted BSP elements and any other meshes appear okay (as you can see above black box in screenshot - those are lit up perfectly as expected).

This is the converted mesh settings:

How do I view that?
