Any chance of making Physics.ray() thread safe? I have to use it on a separate background thread as I'm calling it many times a second, so too much for the main thread. The problem is that sometimes it will randomly crash. I can only assume that it must be trying to cast a ray while the physics simulation is being updated.

When calling Physics.ray(), would it be possible to make the function just wait until the physics simulation update is finished, if it is being updated?

Physics.ray is just a call to raycastClosestShape/raycastAllShapes on physx 2
and raycastSingle/raycastAny/raycastMultiple on physx 3
you can read more about their thread safety in physx docs

That would need to be manually taken care of
