No vis information, direct lighting only.A more complete list of errors is available on the internet here, here, and another one here, although it does not cover features (particularly raised limits) of the newer tools.

This page lists the main problems mappers might come across and the main errors they might experience when using these tools. In-game, only the ones for level 3 and 4 are used.Common Half-Life mapping problems & compile errors - Zoner's Half-Life Tools reference (ZHLT) Common Half-Life mapping problems & compile errors The game's files contain textures for areas that need security levels 5 through 8.

Interestingly, the used textures are called "brdly2", while the unused ones are called "brdly", suggesting the used textures came after the unused textures were made. There is also an unidentifiable logo on the vehicle's side texture that does not appear in the used texture. These textures have a desert camouflage pattern and have much darker lines than the textures used. The metal is of a different style and the "Test Lab" on the upper part is made in the same style as the text on the unused "Control Room" sign.Īn unused set of textures for the M2 Bradley vehicle found in Surface Tension exists. While some of the textures were repurposed (mainly screen images), many were not, leaving them orphaned.Īn alternate version of the sign to the right of the first door that leads to the Anti-Mass Spectrometer can be found. Halflife.wad contains a lot of leftovers from a cut area, the Alien Research Lab, which can be seen in the 1997 prototype.
