Model aircraft hoversurf s3. In scene 3ds max two model white and blue. In other formats, export a single model. Made the animation screws! revolutions are looped without jerk. The screw constantly turns smoothly, when switching from 100 frames to the first jerk does not occur.
-DO NOT REMOVE THE LINK FROM THE MODEL!!!
-THE SCREWS ARE LINKED TO THE MOTOR AND TO THE AXIS.
-good luck with rendering
