I've been trying everything but to no avail. Here's the screenshots: See those lighter spots where the shadow suddenly disappear? The terrain is completely normal and the same all around, the spots have exactly the same materials. This is not the worst case, if i try to shift the sun position lower, they will become useless garbage and very unpredictable.. And they pop up unexpectedly all over the track, if i shift the time of the session. Since i have designed them to be a feature that affects the driving experience a lot, i wouldn't like to remove them or make the sun appear so high that they don't cast any shadows on track. I've tried everything i could think of in the .gdb but can't figure this one out. The shadow objects are custom SObjects, shown here as red/grey: There's an event planned for the next weekend so i would like to got help ASAP. I really don't want to remove one of the highlights of the track, it comes so bland and boring without the shadows.
