TransientDoor is the name of a technical block added by Dimensional Doors. It is presently unknown where, and why this block exists or when it is created. When placed, nothing appears to be there due to the block being completely transparent but attempting to place another block in that same location will fail until a few moments later. When held, it will hide the players hand from the first-person view. The technical block may be thrown onto the ground and then picked up, but cannot be seen due to the transparent nature.
