Need to enable collision without enabling physics impostor

I need to implement the collision for the entire scene and if I dont want collision for a particular mesh I should be able to diable collision.But when I Implement collision its not working without enabling physics(physics impostor).Is there any way to enable collision without enabling physics in the scene?

Hello! Welcome to Babylon.js!

You can do it for example like this:

Or you can check for mesh intersections:


Hii,Thanks for Playground but still the collision is not working in that. If you attach gizmo to any one of the mesh and move it against the other you can see that the collision is not enabled.
