Hi, I had a friend test my game, but he’s getting some really strange issues with lumen:
Those big green and red flashes are not supposed to be there andI can’t replicate it on my end.
Any suggestions on what’s the cause on how to fix it?
Hmm I think it is something to do with the effects system. It seems to happen when you shoot in the game. I suggest looking closer at your VFX and try to narrow down the issue from there.
The red and green colors could be connected to the texture masks from the effect.
You got a really nice game going for you there! Best of luck! 
I quickly enable, then disable a light from the muzzle of the weapons on weapon fire, which I’m sure exacerbates the issue. But it should be the cause so to speak. I guess I could try to lower the brightness and see if players stop reporting it?
I also have green lamps off screen in the direction the glitch is going to.
It seems to be an issue with lumen not being quite sure how to blend in multiple bright light sources when some of them are off screen perhaps?
I specifically forced it to render off screen lights as having their radius “pop” in when the players approaches was very distracting.
