Hi zaboinik, There are two constraints in CTA4: 1. CTA4 will be regarded as 360 degrees as 0 degrees, so it can't make a circle which rotates by 360 degrees directly. 2. The program selects the shortest path to run. It means that If starts from R = 0 to R = 359, and it will walk 1 degree instead of 359 degrees. There are two ways to achieve 360 degree rotation. Please refer to the following link: https://drive.google.com/drive/folders/18n7YSG99BHZ1TvtLB4dWKUFabNG8HPK4?usp=sharing 1. Key by frame You can manually enter the value, but please pay attention to the rotation angle. The video demo is R = 0, R = 179, R = 358, R = 360 2. Elastic motions Apply the elastic motion template and capture the part of the effect you want. If you have any other questions, please let us know any time. Thank you. Soya Reallusion
