Hard to see video played on decal actor

Hello everyone,

I know this is a lighting issue but don’t really know how to fix it. First of all I am trying to play a video via decal actor, the video is black and white. The room itself needs to be dark for a art gallery concept. The only space in the room lit is on the interior of the dome, so I have a point light sphere because the spot light for whatever reason will not show after a light build (it doesn’t even have a red “x” over it and the intensity was cranked all the way up). The point light will work prior to light build but once I have built the light the dome appears to be a black hole. If I move the point light slightly then the decal video will show up. What needs to be done so the decal is visible after the light built without moving the light?

Thanks!
