This chamber was a simple idea, that turned into a nightmare. All I wanted to do was have a drainable goo pit. The only way I could make this work was to have a stationary goo pit, and move the entire world around it with a movelinear. Everything i built had to be turned into a func_brush that was parented to the movelinear. This creates other problems, like a cube that decides to ignore gravity sometimes, and countless lighting issues.
If anyone knows a better way to have a moveable goo pit, please, let me know!
