Thanks for the reply. Lumen is disabled already.
I’m only using a moveable directional and all dynamic shadows
It’s hard to research the issue because everything points to Lumen in search results at the moment.
I’m assuming that’s this is some kind of shadow confusion between the hard edge of the shadow, WPO and the lights direction being updated every frame. But my assumptions don’t mean much as I don’t really know where else to look for improvements.
