The file containing a sample scene is in the Sample Files section with a title of bendexpr.zip. This file shows a problem involving bend and a float expression controller for the bend angle. 1. Create a cylinder with enough length segments to bend it. 2. Apply a bend modifier. 3. Make sure the animation has 100 frames (just so the numbers I give later are correct) 4. In the track view, assign a float expression controller to the bend angle. The expression is 30*sin(360*NT). 5. Frames 50 and 100 will have major problems when the bend angle is at -0.00 and 0.00. Frame 0 is fine with a bend angle of 0.00. 6. Changing the bend angle expression to 30*sin(360*NT)+.01 fixes the problem in this case (no frames have bend angle of 0.00). I've experienced the same problem with other objects. J.J.
