As the name suggests, it is materialized scanning in an intangible glass. It scans anything that tries to enter it. If what tries to go through it is a sack-like thing, the scanner does not become solid. If it is any kind of material that a sack would not usually carry (like bombs, missiles, cars, space ships, sponges, carpets, etc.) that is not Paintinator paint, the Scanner will turn solid until that material ceases friction with the Scanner. For example: Sackboy fires paint, it goes through, Mecha-King Ghidorah fires beam, it does not go through. It's less complicated than it sounds. It made it easier for Sackboy to defeat MKG.
