Proper way to "stream" collider (physic shape) entity in a large scene?

Hi, I am just wondering what is the proper way to "stream" the objects' colliders (physic shape) as the player is approaching that object? I think this is a very common problem in FPS and racing game with a large terrain where you need colliders for trees etc. I am thinking whether I should break down into difference subscenes just like what the Megacity demo is doing but that demo is pretty much unplayable now even if using an old Unity 2019 version so I can't really see it in action. Or I should simply instantiate/destroy the entity according to the player's distance? What is your experience? Thanks.

 

Please see UnityPhysicsSamples/Assets/Tests/StreamingStressTest as an example. If you're interested in detailed pros/cons of each possible approach, I'd recommend asking on DOTS subforum (parent of physics).
