Windows 10, 6000.3.1f1
I’m using the ctrl shift modifier to snap objects to surfaces and it moves the object towards the camera every time I move it in any direction. The object’s parent has a kinematic rigidbody, the object itself and the platform I’m trying to snap it to both have colliders.
Do update, and do so for the next 10+ releases. As with any early release versions there’ll be a higher number of bugs.
Currently an endless spinning rotation bug exists. Yours may be related. Try changing the space dropdown to World and back to Local. If this fixes the behaviour it’s related and will be fixed soon (if not already in 2f1).
Or close and re-open the project. If the behaviour is normal then it’s also likely the same issue (happens only after editing and recompiling scripts).
