What happened to LE 1.x? I remember those days back on the old forums

That didn't have an editor did it? I guess you could just show some code for it

Well, 3D World Studio was the editor, so there isn't really a screenshot of it.

I have 3d World studio, still use it.

wow 3d world studio looks almost identical with source sdk I love it

You can still buy 3d world studio. It's an interesting piece of software.
