I wonder if someone might be able to shed light on something that's always bothered me. On some cars, generally those with separate windscreens as opposed to modern integrated windshields, the windscreen glass material reduces the darkness of the shadows under competitors' cars (or eliminates the shadows completely). This happens regardless of lighting conditions. For example, here's what normal car shadows look like:
But here's what I see through the windscreen:
I'd like the shadows to remain dark. I've fixed it on a couple cars by going into the CM showroom and messing with the values for the glass material, changing the alpha mode from "alpha blending" to "alpha testing" and/or the blend mode from "normal" to "read only." While I have no idea what I'm doing here, this worked for SimDream's Maserati 6CM (for instance), but not for HSS's Alfa Romeo P2.
Does anyone have any idea why this happens and/or how to fix it?
