How can I disable collision between multiple objects?

Unity Engine
1

I have multiple instance of same prefab in scene. I need them not collide with each other. I tried to set their layer and turn collision off in physics manager (edit - project settings- physics) but this does not work. I also tried use Physics.IgnoreLayerCollision but that was useless too.
How can I make it work without removing absolutely all collisions?

you can remove or disable their colliders

you can uncheck the collider to stop it from existing

That is the opposite of what I want.

I need remove collision only between “object” and objects of same type but not the “object” and everything.

But somehow even that does not work

Well… I found the problem, but not its solution. Problem that NavMeshAgent that I use prevents them from passing through each other.

For the problem of disabling collision between two colliders you can call Physics.IgnoreCollision after instancing the prefabs.

(Sorry, I can’t help if the problem is with the nav meshes, I don’t have any experience with them).
