Assign different Physics for each material?

    I have a gameObject that contains two different Materials. (Water and Earth). Now I want to both of these Materials to behave differently when another object falls onto them.

    What do I have to change to be able to assign a physics object to those materials?

    (I added a screenshot of the inspector to - hopefully - make my problem a bit clearer)

    This could mean anything TBH.

    Not sure what you mean by a "physics object". The supported options for automatic behavioural changes is done using physics materials (3D).

    Thanks for your response

    Yes I meant physics materials which I already created.

    I can add that material to the Mesh Collider but then the physics is assigned to the whole GameObject. I want to assign it to the two materials of the mesh renderer instead. (each material having a different phyiscs, especially dynamic friction)
    But the Mesh renderer does not allow physics materials as elements

    GameObjects and renderers have nothing to do with physics interactions; they are for visuals only. A render material has nothing to do with physics materials.

    No, it's related to that Collider; the GameObject is just a container of components and is nothing to do with physics.
