Btw I figured out what was the problem with the reflections. I had a TAB behind the object names in the REFLECTEDENV section... The only remaining problem is the shadowrange. If we can solve it I'm going to release the track.
I've seen all of your videos, nice piece of work/help! Unfortunately the shadow mip bias doesn't help.
I tried to remove the "Maxshadowrange" line from the .scn. In Devmode you can see the difference, the shadows come up very close to the car like it's set to 50 or something. In the game there is no difference at all, the shadows come up at the same distance as before, it's always the same no matter the value. I also tried to use Groupmethod=Linksingle instead of Dynamic and it changed nothing (btw I have no idea what this does). Conclusion: these lines (fog, light, maxshadowrange, ambient, groupmethod) in the .scn are worthless so why are they there?
