@lorelord, to have a proper paint coloured LoD D when using the CM LOD generator:
Open CM Showroom and click on a car paint mesh to find out its
material name
Copy/Paste that name into Car paint meshes in the LOD generator and add "material:" in front of it (without the quote marks)
So this box for the Noble now reads
material:Material #648
Generate the LODs as per usual
No idea why Ilja didn't set this up so that LOD D does this automatically in the generator, black LOD D's are visible out on the track and look daft.
(thanks to
@norms for the notes)
