I have point lights, stationary still showing in reflections despite roughness minimum of 1. Trying to remove it all togeather, using forward rendering, curious if this is why
I have experienced the same problem with forward rendering. I can confirm that when I switch to deferred rendering the problem disappears. I have tested this on my current project and on an empty project in 4.15
Apparently it is a bug. It has been reported: Unreal Engine Issues and Bug Tracker (UE-42488)
Be a workaround or not. Setting to static you can get the reflection to go away.
