Transfer Grabbable is a component that is used to mark objects that undergo Transcient Grabbing, but only while in Userspace. The grabber during this process saves the object into memory including materials, then simulates a paste as it puts the object into the target world.
If the world does not allow transferring to it, the _indicatorMaterial material will replace materials on the object and light up red. Will restore the materials back if transferring is allowed to the target world.
