I cant get refractive materials to bend a beam of light. I passed a beam of light (parallel, volume, infinite) right through an object that had an assigned glass material. Regardless of which refractive setting is used, the light beam itself passes through without bending like it should. (I also tried other types of lights, and light settings with the same result.) Scenes viewed through the same object are distorted by the materials refractivity; as they should be; however, the light beam itself slices through the object, and emerges unbent. See page 218 of the Bryce 4.0 manual for a picture that illustrates how a beam of light would be bent in the real world. I reproduced this scene in Bryce, but the beam wont bend. Anyone know why? I presume it has something to do with the way Bryce raytraces. Or am I doing something wrong?
