Hey guys, I need some help, as I can't find anything about this issue on Google...
There is light shining through the ceiling edges of my tunnels. You can see it for example in my last video at 2:14:
So I thought my mesh had a weird structure and I made a really simple tunnel in Blender for testing purposes. I created a cube, stretched in on the Y axis, inset the two remaining square faces and bridged them. There I got the same effect. So next I tried bevelling the ceiling edge and bevelling it a bit more. Also I tried adding another cuboid to the edge in two different sizes. It's all the same basically.
Here are some screenshots of this process
(don't mind the missing face, I accidentally deleted it but it doesn't matter)
It also seems to have something to do with shadow LODs, because it gets even worse 20 or 30 meters ahead of my car. So I thought maybe it just looks this crappy on my side because of some misconfiguration of AC or CSP? But I haven't found anything I could change, either. Also I tried
@LilSki 's Watkins Glen yesterday just for fun, where I also noticed the same shadow LOD effect on fence shadows (the shadow resolution get's really bad 20-30 meters ahead). Have I just never noticed this before in AC?
Edit:
it seems like adding a plane clipping through the tunnel partly resolves the problem, except for the edges:

I'm still not super happy with this solution though
