Can somebody please do me a favour and insert this light fitting into a new project, export to a 3D DWF and see if the light source is solid?
I'm still having the problem of the light source showing as solid in all my 3D DWFs on any fitting that wasn't made by Autodesk. This fitting is one I haven't made, it was downloaded from VISA lighting. If you don't see the light source then it is the templates I'm using.
Still see the light source on this fitting by the way, and any of mine, but not default fittings.
