My Hammer has no Grid, or I get “Failed to load the default scheme file.”
You may have no grid, or get this error when you load Hammer.This is most likely because you have launched Hammer from Source SDK. This is no longer how we load Hammer for games without Authoring tools. (Counter-Strike Source, TeamFortress 2, ect..) Instead you should be launching Hammer.bat (Launch Hammer.exe if the bat file fails) from the BIN folder. The path to TF2’s BIN folder is: Steam\SteamApps\common\Team Fortress 2\bin. Once you load Hammer from the BIN folder, you should no longer have this issue.
