When I practice with KartSim rental karts at 397's Quebec Superkarts track, there is an effect turned on that makes it seem like the sun is going behind the clouds, but it's way more pronounced in VR and it's hard to see when that happens. I'm watching the replays and it was hard to see the effect on the monitor compared to VR. I looked through the settings and find one called "Sun Occusion", but it's already turned off. I told Reddit and they think it might be a bug with the exposure and told me to report it at your forum. I hope it's just a setting I can tweak/turn off though. Thanks!
