MILITARYMAN, ah, you just added "Light Markers" to your level, correct? Not models of lights?
After choosing a "light marker" in the editor one can use the Bracket keys " [ ] " to
increase or decrease it's radius, or "right click" it to open the lights properties settings.
When doing a "Test Run" one can also adjust "Ambience" with the " < > " keys during testing.
Note: that's for the ambience setting, not the light markers. See if that helps during a quick test run?
Also, just had a thought, have you installed DX9 yet? If not, you need it to run fpsc correctly.
Grab the DX9-c standalone version off line somewhere. Even if you have DX10 or 11
there are some files still missing that DX9 has that are needed.
My games never have bugs. They just develop random features..
Lots and lots of random features...
