I've upgraded to x9. When I raytrace from a camera view my finish product is missing floor and ceiling surfaces. I'm not sure if this is a glitch or a setting I'm missing. I am using the full camera and I do not have any breaks in the wall. Is this happening to anyone else. It has happened on both my PC's. Video card is not an issue and I did not have this problem with x8. I'll add a picture that was run on 5 passes but none of the quality settings make any difference in the end result.
