Jason, thank you for the advices.
- Chandelier really looks like if it was an emitter as a whole, but as far as i understand, it shouldn't be an emitter as character type = Auto.
- It takes ages to render to SL20 (i think around 16 h last time) that's why I've replaced glass with AGS, but I see what you mean, I need to reconsider glass.
I've attached zip with the .skp(sorry .skp is too heavy to attach to the thread).
PS: I use "Walls" layer to hide/show walls if I need to adjust the view.
