Another nice environment i converted from DAZ.
For the lighting i used spotlights in addition to glow textures.
I have done a comparison of how my setup bahaves in iClone native and Iray render.

I don't know why the iClone spotlights are so limited.
It is not possible to place a spotlight behind the glass globe of a roof lamp.
Also, the light emission of the glow channel has a remarkable behaviour (the hot stones!).
Any suggestions and hints welcome.
