ForceMode.VelocityChange and Friction.

Hi

I'd like to move an object using AddForceAtPosition and ForceMode.VelocityChange but it's impacted by friction and gravity. If the speed is too low, my object is stucked.

Is there any way too disable friction between 2 rigidbodies ? (except by changing their materials)

Thanks

 

Zoomed out a bit, what are you trying to do?

If it's move an object outside of physics entirely you might be better off with Rigidbody.MovePosition: http://docs.unity3d.com/ScriptReference/Rigidbody.MovePosition.html

 

I 'd like to do a kind of conveyor belt.
I've already tried Rigidbody.MovePosition.
AddForceAtPosition with ForceMode.VelocityChange looks more realistic, particularly when other collisions involved.

Thx.
