What is this weird cone of light with ortho camera?

i have this weird cone of light and follows my camera wherever i go…
it only appears when i use ortho view, but it all looks fine with perspective camera

how can i make it gone?

Hi Yanzco,

This is a known issue with Orthographic view caused with lighting. You can vote on and track the issue here on our public tracker: Unreal Engine Issues and Bug Tracker (UE-11446)

In order for this to be gone, either use statically lit environments with no stationary or movable lights, adjust the roughness of the material to have not have any reflections or not use lighting and make the materials use the unlit option.
