Glass Problem
Im having problems with glass in LS couse I get strange black splotches when RayTracing.
My model doesnt have any too small polys so nothing dissapears when I render model like ideal diffuse material. Do I have to model "air polys" for the glass (offset the surface of the glass to the inside and make reffraction index 1.0,also reverse the direction of normals), wich I did but problem ocures again. Heres a screenshot of my model (revolved curves). Whats the trick?

Re: Glass Problem
You do not need the inner surface, just use the outter one (red in your example). Otherwise, make sure you have a high enough ray bounce--you're using up 8 bounces just getting through all those glass surfaces. Is the background black? If it's reflecting, perhaps put in some lighter 'cards' to reflect.

Re: Glass Problem
Ray bounce is up at 10. I dint change it.
What do you mean by black background? The model is interior, illuminated by the sunlight. All wall surfaces that are sourounding the glass are white. Theres also the "window" surface but its also white colour. Theres nothing black to reflect.
