Great insight Pete. Yes, if I change the y value to 100, the floor no longer gets clipped.
But I do want the camera at a height of 12. My problem is I dont really understand quite how these focus and zoom values work in away3d. How do I know what values to put for focus and zoom for this to work properly?
