@hellothankyou I've just realised that the rain glass/wipers mod you did for the M5 pack stops direct sunlight from casting shadows in the cockpit.
I archived your modded M5s and redownloaded the originals from Assettoland again and sure enough, the original cars allow direct sun to cast shadows on the cockpit. In the modded versions there's just ambient light in the cockpit but no direct sun/shadow contrast.
Any ideas why that would be?
It can hopefully be fixed because shadows playing across the cockpit, dashboard, steering wheel etc is really important for realism and immersion.
Mmmm... makes me wonder now if ALL RainFX-prepped windscreens have this unfortunate side effect.
Edit: nope, the Kunos E30 M3 for example works with RainFX and has proper sunlight penetration.
