[Closed] Dynamic lighting artifacts on spheres
I have an issue when using a dynamic light on spheres : on the side with the shadow/light boundary, if viewed up close, you can see lighting artifacts. The artifact consists of noticeable lines on the surface.
The following screenshot was taken in "detail lighting" rendering mode on the "EditorSphere" mesh included with UE. Copy/paste the image URL in your browser if you don't see the issue.
I'm using UE 4.7.6. The light is a directional light.

These lines are caused by the Cascaded Shadow Maps.
You can adjust the settings in the CSM tab in the Light Source and try adjusting the Shadow Bias & Shadow Filter Sharpen for better results, but it will not necessarily get rid of this completely and changes can affect other objects in the your scene if you're not careful. It's about finding a balance to what's acceptable and what's not when adjusting the CSM for dynamic directional lights.
You can see some examples in our Wiki Lighting Troubleshooting and Tips guider here: wiki.unrealengine.com/LightingTroubleshootingGuide
