Ok I installed Earth Dynamic Sky and added the enhanced_sky 1 to cam_ext.cfg and got this http://img839.imageshack.us/img839/7163/dump000.png
I assume I edited the wrong .cfg file. I will try some others and report back.
*EDIT* I also tried adding the enhanced_sky 1 to cam.cfg and all I got was the original SS2 sky from 1999 :/
I know I must be doing something wrong. Anyone have any tips on what to try? All these mods seem to work though,
SHTUP (hires object textures)
Four Hundred (hires world textures)
Vurt's Space (hires space textures)
SHMUP (better quality original music)
