It wont show inside the editor window, but if i move it out and onto my desktop area it shows.
Oh god...not this again...you need to run d3radiant in windowed mode, with antialiasing disabled for it to work. Create a new shortcut to you doom3.exe, open properties, go to the shortcut path, and add "+set r_fullscreen 0" at the end, without quotes of course.
as a rule give us as much info about your system so we can help you in the futer good luck :smokin:
Thanks. That solved my problem. I'll be more specific in the future.
