Texture replacement editor for the Quake 3 map format


Chameleon is a standalone GUI-based texture replacement editor written in Python and PyQt. Its main task is replacing a number of textures inside a .map file while applying scale factors and rotation to all affected surfaces. It allows you to:

  • Replace old-fashioned textures with high resolution ones without loosing the alignment
  • Choose the target shader/texture from a cached database
  • Create and export replacement rulesets for later use


  • Python >= 3.3
  • PyQt4
  • Pillow
OS Dependency names
Arch Linux python python-pyqt4 python-pillow
Debian python3 python3-pyqt4 python3-pil


Manual installation

After installing the dependencies, just run with Python.


OS Package
Arch Linux q3chameleon-git


Always make a backup of your map! It is recommended that you export the updated map under another name instead of overwriting the old map.
