Here we see the basics of the core mechanic. Grabbing an object turns on a point light and a particle system which signal where the object is to be placed. When the object is brought to the empty box collider hovering over the particle system and light, the particle system is turned off. It will be a simple matter to get the collider to also turn off the light.

The next step is to trying and create a system that snaps the objects into place when they trigger the collision and the grab has ended. I struggled with implementing the OVRGrabbable scripts isGrabbed bool before but ideally I would use an if statement to see if the grab has ended and the collider has been triggered and then do a transform to the designated location.
