Hey guys! So I am having this issue and I can not get it solved for the life of me. Basically I have my fx rendering so it should be showing up in radiant when in the light preview mode, but it isn't. When I open up one of my other maps the fx lights appear just fine but for whatever reason they are not showing up for this one map that I am working on. They also are not appearing in game either. When I click the lightning bolt to build my lighting the glow from the fx lights appear for a second and then go back to not showing. I thought compiling the level would fix it and it would show up in game but they also are not showing up in game. Any help would be much appreciated as this is very frustrating! Thank you in advance!
So I managed to figure out what my issue was. I had my sun volume's skybox/sun set to "default_day". I realized that since it was a daytime sunlight the fx's fire omni lights were not bright enough to appear. I fixed this issue by switching my sun volume from "default_day" to "zm_factory". This basically made it so it was moonlight in my map instead of sunlight. Since the sun's light was darker the fire omni fx lights appeared once again. Hopefully this helps someone!
