Actor Surface Light Problem

Hi my friends.
I have a problem like the photo. There are two objects as wall and facade. As you approach each other, a helix is formed as follows. It’s causing a bad picture.
**How can I prevent these apartments from forming? **

Thanks all of you!


That is due to the dynamic shadows, it can be adjusted with the Shadow bias setting though that will affect how close the shadows will line up to the object that casts it. If you are using static lighting then make sure to build the lighting because it won’t have that issue.

Also, moving this to the Rendering section
