Hi, I noticed this just lately and wanted to share.
REMEMBER TO UPDATE TO LATEST VERSION OF FPSC
HERE IS THE SUNLIGHT TUTORIAL
Open setup.ini and change the lines as following:
lightmapsunx=1
lightmapsuny=-1
lightmapsunz=0
lightmapsunr=255
lightmapsung=255
lightmapsunb=255
if you want to include this when you build your game, also edit buildsetup.ini
The sun will now be on the left side of the editor.
For realism you can edit the location of the light to mach your skybox by changing the .ini file
HERE IS THE LIGHTRAY TUTORIAL
Again, open setup.ini
And edit the following:
Now you have lightrays!
These will be positioned to the top of the map editor.
This can be changed in-game with "page up" and "page down" buttons.
hope this help
