New Update, I can see a yellow dot in this panel, the yellow dot seem to be the unreal scene as i can move around the dot. but couldnt find out what's the issue. Seems like there's something wrong with the camera in unreal engine as i couldnt even get a content from the ue4 file's output

Problem solved, adjust the exposure value under the LEDWALLCAM compound, you'll see the scene. for some reason the exposure was 0. The Yellow spot is the sun in the scene BTW. Hope this post helps someone. :D

Hi Christopher,

Thank you for sharing the solution!

Yes, for certain reasons our LEDwall blueprint does not support auto exposure. That means if your scene is too dark by default you have use the Exposure on the control board.
