Failed to load the default scheme file

From Valve Developer Community

Image:Todo.png To do: Verify if this issue is still present in the latest releases of the Source SDK.

Error message: 

"Failed to load the default scheme file. The map views may be missing some visual elements"

[edit]

Possible causes

The error is known to occur when when trying to start hammer faster using a shortcut, instead of the Source SDK GUI.

[edit]

Possible fixes

  1. Get SourceScheme.res from one of the GCF files or create a mod.
  2. Copy it to the ...\SteamApps\username\sourcesdk\bin\resource\ folder, or to the ...\SteamApps\username\half-life 2\hl2\resource\ folder.

If this doesn't work, then you can use Filemon from sysinternal's to find out where Hammer is actually looking for this file.
