Short description of error
Note I currently have only tested rigid body physics, this might affect other physics types as well.
The issue is that changing the frame rate after physics have been assigned to an object will change the speed of the animation.
Exact steps for others to reproduce the error
- Add rigid body physics to default cube
- Play animation. the cube should fall about 5 meters (4.905 to be exact) after the default 24 frames (1 sec)
- Change frame rate to 60
- Play animation. the cube should fall about 5 meters (4.905 to be exact) after 60 frames (1 sec)
- Animation is the same even after clearing and rebaking the cache. The only solution I found is to add and remove the rigid body physics.
