Caveat emptor: HedgeHog 12's 'Better Rain' mod will cause screen darkening with MGE distantland active when using any of the 'Raindrop' meshes with extended texture mapping effects like bump, detail, gloss, etc. However, any of the _x.4 versions should work ok.
Oh my, how odd. I was just wondering why my screen got so black and dark. I've tried to figure it out and got irritated, so I quit. Decided to do something else and there you go, answering it for me. Although I read the readme, I forgot that detail. Thank you.
