I posted this on the RTB forums, but nobody there responded. I'm posting it here, as I would really like to see coronas.
For some reason, fxSunLights do not work correctly for me. They used to quite a long time ago, but now they do not show up until the center of the corona is not visible. So, if I looked directly at it, the corona would not appear. If I look away, you can see the corona just fine.
Another possibly related problem is that lights only display from the corners of bricks. Standing on the center of a large cube with the player light on does not light it. Standing on the corner does.
All other coronas work just fine.
So, does anyone know what's wrong, or better yet, how to fix this?
