PMJI- I've been a little out in the woods on this flip thing, too.. I seem to be having a similar problem w/ a camera movement in R2. I found that when I dive the camera down the inside of an open-ended cylinder it jerks a 180 deg roll every 8th frame or so. Very puzzling, it was. I tried doing the reverse-roll-at-the-frame maneuver to counteract it and started getting into complicated keyframe manipulation that seemed a little.. well, excessive. Is this the same sort of thing? Are there "singularities" imbedded somewhere in the walls of my cylinder, as well, yanking the camera this way & that? My workaround was to simply throw out the offending camera path/keyframes and leave it stationary, while making the cylinder shrink down its length from one end, giving the illusion of camera movement. Seems to work OK, sort of. It kinda flies in the face, tho, of advice I received in a 3D animation course for this kind of motion, i.e., "Move the camera & leave the objects alone if possible..". (BTW are they by any chance the same kind of singularities that black holes become, a la Stephen Hawking…? (<g>juskiddin)). Best regards, John Gummere =SP=
