Shadows
I am a shadow freak with Source. So here’s a bit of terminology that you probably won’t even understand.
THESE ARE LIGHTMAPPED SHADOWS WITH 2 LUXEL UNITS. THE OBJECTS IN THE PICTURE ARE A PROP_STATIC (SIGN), 2 PROP_PHYSICS SET TO MOTION DISABLED AND SHADOWS TURNED OFF, AND SOME BLOCKLIGHT BRUSHES, SIMULATING STATIC SHADOWS FOR THEM.
Whew, well, hopefully these will get your attention in the next Cloned Cube update!
