Hello.
I seen this problem at version UE4 4.13, and after updating to 4.14.1 this problem persists.
In BP SkySphere I change cloud density and light intensity (for realism). When I try to connect “Set Occlusion Mask Darkness” and “Light component”, an error - “Light Component Reference is not compatible with Directional Light Component Reference.”
How I can change Occlusion Mask Darkness into Blueprint SkySphere?
