I try to use 1DOF rotation as a dynamic mesh for the motion of the gears ( there are two gears including driver and driven gears). I set one 1DOF for the driver and another 1DOF for the driven gears. I also define the angular velocity but unfortunately there is no motion in the preview! There is a warning which is "Warning: unable to read motion history file". I would be so grateful if anybody can give me any solution for this? Best regards
