Sort of, you probably need to use a catalogue and the FurnitureLibraryEditor (.obj does not support light-sources). But in the library file ([font=courier new]PluginFurnitureCatalog.properties[/font]) you can set the colour of the light-source (very simplified approach described on page 10 of the the SVG guide).

Possibly, you can also set a semi-transparent lamp-shade in the .mtl file to the correct colour, but I am still struggling with getting the right effect when light shines through. ok
