Duplicate object, how to avoid collision between them ?

Question

Hello, I didn't found the answer of my question so here it is:

I have a KinematicBody (3d) which I place in my main scene and I duplicate It a couple time.

How to avoid collision between them ? They can move and I want them to avoid collision between every copy of this object.

There is no function for ignore collision for all object in the same group ?

I have to deal with the collision layer & mask ? But what if there is more than 32 of this object ?

Hope someone can help me.

This is a tough one to explain, so I'll defer to the docs: https://docs.godotengine.org/en/stable/tutorials/physics/physics_introduction.html#collision-layers-and-masks

Yes, you will use layers and masks. Each 'duplicate' belongs in a layer, which essentially groups every object together (one layer, many objects). By grouping them together a mask can ignore the layer and the objects won't collide with each other. The documentation explains this well.
