So as my camera gets further away from the spotlights pointing upward they eventually fade from view at a certain distance. After doing some digging it seems that Max Draw Distance may be reason but I have middle mouse measured the distance and have it set to a higher number.
Also I have a flashing tower light in the bottom right of the image towards the end that also culls from the view at a certain distance which is an instanced static mesh.
Can anyone help?
