Problem with Setting Friction Parameters for an Actor

[SumeetBatra]

Hi all. Following the tutorial you all provided, I'm trying to do some simple physics domain randomizations of the cube in the PickCube task like so:

        for obj in self.cube._objs:
            # modify cube friction
            dyn_friction_range = self.domain_rand_cfg['cube']['dyn_friction_range']
            static_friction_range = self.domain_rand_cfg['cube']['static_friction_range']
            for shape in obj.components[1].collision_shapes:
                shape.physical_material.dynamic_friction += np.random.uniform(
                dyn_friction_range[0], dyn_friction_range[1])
                shape.physical_material.static_friction += np.random.uniform(
                static_friction_range[0], static_friction_range[1])

However when I do this, it seems that setting the friction values for one object in self.cube._objs sets the same values for all the actor objects. Is this a bug or am I doing something wrong? Thanks!

This sounds like a bug. Could you help print the object id

# something like this
print(id(shape), id(shape.physical_material))
