Leaked VMF Names

In an early leaked version of the Robot Repair demo, slightly earlier versions of Portal 2's materials, models, textures, particles, and sounds can be found converted to Source 2 (using source1import) in a folder named portal2_imported. In order to convert maps, the tool was also given all vmf map source files, including a huge number of unused maps and instances from different stages of development (as they were never deleted, most of them just moved to a folder named "scratch"), development and styleguide maps, and even all maps from the development of Portal 1. The maps were deleted afterwards, as they were not required for the Robot Repair demo.

However, because the Source 2 Asset Browser was opened before the deletion, all the names of the converted maps (and the folders they were in) were backed up in a file named readonly_tools_asset_info.bin. This means that we now have almost every single map and instance made during the development of Portal 1 (already leaked), F-Stop, and Portal 2. A part of these map names can still be found as leftover reslists, giving a full list of assets used in the map.

Likely or known F-Stop
puzzle_ maps, some of the earliest maps made. Main campaign maps, mostly having reslists. These were likely the maps used during the big internal playtest that led to the cancellation of F-Stop. Mouse trap maps, the mousetrap mechanic was only seen in early concept art. Fan mechanic, fans would move objects in the direction they were facing. Aperture Training maps, probably early story maps. Maps for the chicken mechanic, including a farm Maps for the dollhouse mechanic, including a demo? Maps for the cave diorama. One of these maps might be from later Portal 2 development (where the diorama was briefly reused) Other maps (some of these might not be F-Stop) That's all for F-Stop. The rest of this page is about Portal 2's development.

P2 Styleguide Maps
These would be example maps of how something should look like,

Zoo test maps
Zoo maps are usually maps containing a lot of stuff to quickly test something out.
