Hey Hexy, here's what you'll want to do -
Open up your FPS Creator folder, found at
C:\Program Files\The Game Creators\FPS Creator
Amidst the files and folders within, you should see a text document that
should open in
Notepad when you double-click it. The file is called "setup".
Once you have this open, you should see a plethora of different settings you can tinker with, here's the particular section you'll be dealing with
[GAMEMAKE]
lightmapping=1
lightmapold=0
lightmapshadows=0
lightmapambientr=0
lightmapambientg=0
lightmapambientb=0
lightmapsunx=0
lightmapsuny=-1
lightmapsunz=0
lightmapsunr=0
lightmapsung=0
lightmapsunb=0
lightmapzerorange=100
lightmapatten=16
lightmapmaxsize=-1
lightmapboost=4
lightmaptexsize=512
lightmapquality=100
lightmapblurmode=1
lightmapthreadmax=-1
bloodonfloor=0
imageblockmode=1
For recommended settings (for shadows), set
lightmapquality= to somewhere between 80 - 100.
Doing this allows you to get those very defined and sharp shadows such as those in the screenshot I've provided.
Hope this has helped shed some light on your question
Cheers
Life would be much easier if I had the source code.
