BEE2 UCP and model for the glass cube item. Included is a vmf for usage in Hammer. To use in BEE just add the glass cube package zip file found inside the main folder to the BEE packages folder. This item functions as a cube which lets lasers go through it and cannot be painted with gels. Its ghost cube does not block lasers either. This is a more niche puzzle element and is a lot harder to use than most other elements but can be used for very complex laser logic. Credit as Nuclear Shill.
