Ue5 City Sample Crowd - Black Shadow Artefacts on Characters

Please see screenshot attached. Can anyone help, dont know why there are these artefacts showing up on the characters. Im using a laptop RTX 2070. Also in the pic below I’ve added Cell phone animation and cup animation to characters but the cell phone and cup dont appear when I choose the animation.

Now I also have issues with the eye shading. See Below, any help would be very much appreciated. Thanks

hi ,
i have same issue do you found a solution ?

No, unfortunately not. I had to replace the Crowds City Sample Metahumans with Methumans from The Metahumans online Creator for hero people then try blend in the crowds in the Background.

hi,
thank you for your quick response .
i think I found why , it’s because raytracing shadow and lumen
here is a workaround. but if you need raytrace , I am not sure how to fix this

Have nice sunday.
Best regards
Daniel
