Description

While compiling or attempting to play it, your map has hit some sort of memory limit.

Causes

Almost anything can cause this error.

  • A brush entity is too large. (most common)
  • Not enough system RAM. At least 128 mb is recommended.
  • Byproduct of a leaf saw into leaf error.
  • File pathnames are too long.
  • Too many textures/WAD files being used.
  • The level is simply too large in general.
  • Too many SKY faces on hidden brush faces in the level.

Solution

  • (Compile) Get more system RAM.
  • (Compile) Try using a third-party compile tool interface to compile your map, instead of the Run Map interface in Hammer. This will free up more system memory to allocate to your map compile.
  • (Compile) Check for any overly large brush entities, such as large trigger_hurt entities.
  • (In-game) Some rendering properties may cause the OpenGL or Direct3D renderer to crash. Try testing the map in the Software renderer.
