NoteIn non-Revit to 3ds Max workflows, the 3ds Max FBX Plug-in does not support Skylights (and their targets). Instead the plug-in converts them to null objects. The plug-in also converts mr Lights to Standard lights (for example, an mr Area Omni light becomes a Standard Omni light) and Photometric lights become Standard lights (where they lose any Photometric-specific values).
