GtkRadiant 1.5 has a common problem that's thankfully relatively easy to fix. On starting up the editor a quick look at the console will reveal the following error message in red letters;
Unable to find default tag file [drive://directory/path]/shadertags.xml. No tag support
Assuming the error isn't popping up as part of
the wglMakeCurrent error
, do the following;
- Go to the"Plugins" menu
- And select "ShaderPlug » Create tag file"
This will create the missing shadertag.xml
file in your 'user' folder (C://Users/ for Windows Vista) and tell you to reboot. On doing so the error message will now be gone.
