How should i create the box mesh to use as a trigger zone... I really want a non-visible box area to walk thru and trigger and event. I get that i can use the action manager and or just check intersects with in update loop. But i can trying to add support for trigger volumes to my BabylonsJS Toolkit and i am creating the box using the babylon.entities api in C#. So i guess what i an asking is 'HOW MUCH' of a regular cube mesh do i need to create for it to be a non-visible at runtime ar
