I am working on a 3D project consist of an experiment in chemistry. I am facing some problems while rendering the multiple layers of objects with Glass shader applied on them. My scene consist of one big Trough (glass tub) in it water is present and in the center of trough a glass jar is placed and from the bottom of glass jar a glass tube or pipe is passing out toward upward direction.
Please check the attached file for this...
