Portal 2 Puzzle Maker/FAQ
Q: Will the Puzzle Maker be made available on the 360 and PS3 versions of Portal 2?
A: For now, the editing in Puzzle Maker and consuming puzzles via the Portal 2 Workshop will be for PC and Mac versions only.
Q: Why can't Turrets shoot through portals?
A: This is intentional and by design. During the game's development, turrets could shoot through portals. This led to several bad experiences where playtesters would place a portal and then instantly get mowed down by bullets from an unseen direction. It often wasn't clear to players that it was a result if something they had done, and it really interfered with puzzle-solving. Changing it so that turrets can't shoot through portals helped a lot, and allowed for better puzzles in general.
Q: When you edit a published map and save it, does it update the published version without having to republish?
A: No. When you make changes to an already published map, those changes are local-only. (The word 'Published' gets a little star next to it to indicate that what you have is out of sync.) To make the changes live, you must re-publish.
Q: Does Puzzle Maker replace Hammer or make the Authoring Tools obsolete?
A: The Puzzle Maker doesn't replace Hammer or the Portal 2 Authoring Tools in any way. It is meant to compliment them. Authors are free to use one or the other as they see fit. In fact, many Hammer users choose to use both.
Q: Can authors export chambers made in Puzzle Maker to Hammer/Portal 2 Authoring Tools?
A: Yes. Puzzle Maker exports VMF format files that can be opened directly in Hammer for further fine tuning.
Q: How about the other way? Can you export Hammer files back to the Puzzle Maker?
A: No. The export is one-way only, from Puzzle Maker to Hammer. Hammer is a very advanced and generalized tool, whereas the Puzzle Maker is totally focused on Portal 2 puzzle chambers. There's no way to easily allow Puzzle Maker to read VMF files.
