Error reading weapon data file for: weapon cubemap

This error occurs when a mod doesn't have the weapon script file for weapon_cubemap in the mod's directory.

Fix

If you're trying to get weapon_cubemap working in a mod, you will have to extract the weapon_cubemap script (hl2\scripts\weapon_cubemap.txt) from the source engine.gcf archive, to the mod's scripts folder. (For example: SteamInstallPath\SteamApps\username\counter-strike source\cstrike\scripts\)
