I’m having environements like a city or a populated room with objects and stuff.
They al need to have collision so that characters don’t walk through them.

But they’re not just 1 object. they’re many. Can i select them all and apply Collision collider and rigidbody at once?

Select all, choose Add Component, choose Box Collider and you’re done.

You might need to tweak the collider size for some items.

Another option is to export a collision geometry along with the environment and just enable the collision flag on this one.
