Installation on Call of Pripyat

1. Download archive that you want.
2. Rename original bin folder to some other name (for example, bin_backup).
3. Extract the archive to the game root folder.
4. Launch the game using original launcher Stalker-COP.exe.
   • If you have OpenAL: Can't create sound device. error, then install OpenAL using oalinst.exe from the archive.
     • In nightly builds oalinst.exe is missing, because the error is fixed.

Installation on Clear Sky

2. Rename original bin folder to some other name (for example, bin_backup).
3. Extract bin folder (ONLY!!!) from the archive to the game root folder.

   • gamedata.zip – if you use December 2021 RC1 release of OpenXRay.
   • gamedata.zip – if you use use latest nightly build of OpenXRay.

Installation for mods

OpenXRay is compatible with most original mods for COP, but there are few things to consider:

• Compatibility with mods that use modified engine is not guaranteed (OpenXRay is a modified engine itself, so no compatibility with other engines).
• Engine is less tolerant to errors in mods, so it may crash or won't even load where original X-Ray would ignore the error (but that might lead to strange bugs or even saves corruption). We plan to return compatibility with original engine and ignore some of the errors in player's version of the engine.

Installation steps per se:

1. Download archive that you want.
2. Rename original bin folder to some other name (for example, bin_backup).
3. Install mod first.
4. Extract only bin folder from the OpenXRay archive to the game root folder.
