Despite having a 32-bit integer available to be used, most flags go unused. Vanilla Quake and GoldSrc only use TEX_SPECIAL.
| Flag | Name | Notes |
|---|---|---|
| 0x00000001 | TEX_SPECIAL | |
| 0x00000002 | TEX_MISSING | Used by fitzquake and derivatives to indicate a missing texture |
| 0x00000800 | ??? | Used by VERTEXNORMALS BSPX lump |
Contents types
Contents are stored as a signed 32-bit integer, and are always negative.
Ambient Types
Ambients are stored as an array of 4 unsigned bytes, indicating volume. Only Quake uses them, and it only uses AMBIENT_SKY and AMBIENT_WATER, which are hardcoded in the engine to play specific sounds when a visleaf containing the given ambient type is in the current PVS.
| Index | Header text | Header text |
|---|---|---|
| 0 | AMBIENT_WATER | |
| 1 | AMBIENT_SKY | |
| 2 | AMBIENT_SLIME | |
| 3 | AMBIENT_LAVA |
