I just recently upgraded my 3090 to a 5090, Twinmotion is my preferred choice when it comes to exterior renders unfortunately I have a scene which previously was working fine.
Like the title says I have a vehicle path set at night time with motion and there are only a few cars with lights the other ones are not showing in the viewport nor the rendered image.
I did test different configurations, apparently for some odd reason, I have to put the timer all the way to 00:00PM Midnight which previously you have to just up the slider until is dark say 21:00.
Anyways trouble resolved I will leave the post in case someone else find it useful.
