Question How to create perfect 3D Physics?

So I'm trying to make a game where you move a group of rectangles ( by using AddForce ) to make a path for the main rectangle to go. the level design isn't important for my question.

The problem is, that the edges usually collide, although they shouldn't.

So my question is:
How do I create a game with 'perfect' physics?
Which movement method should I use?
Which collision system should I use?
Do you have any tutorials to recommend?

Thanks in advance

 

Hello,

Try creating a new Physics Material. Set its Dynamic Friction property to 0, then assign it to your colliders.
Let me know if that helped.
