Gyroscopes and look at rotators cause movable objects to slide
Attach a very strong gyroscope to a movable object, and set it to align all axes. Orient it so the object is tilted when the gyroscope is keeping it upright.
Start time and let it fall to the ground. Look closely and observe that the object slowly slides across the ground.
See attached video.
We can confirm that the behaviour outlined in your video is expected behaviour and we suggest that you use a Mover gadget to remedy the movement of the sculpt. Although the video example is basic, this fix might not be applicable in all cases.
If we could get more information from your creation, we can investigate further.
It doesn’t relate to the object hitting the ground and sliding because it happens even with objects that are lying almost flat when the rotators are turned on and set to rotate to an orientation that is very nearly flat. Additionally, it causes objects to slide more on sloped surfaces. Setting friction to 100% on both the rotating object and the ground stops the sliding, but has other unwanted effects and is tedious to set up for every surface.
I have a feeling this is just because it's not damped in any way. It's rotating the object, but has no bearing on movement. When it falls to the ground, it generally moved a little to one side, and then it continued to move in the direction it moved it I think? Try adding a mover for a split second and see if when it hits the ground it continues in that direction because there's no damping.
