Hello reckless,
the only thing that I dont like are the extreme shiny "wet" surfaces.
That gives a plastic look (just like the _gloss textures in DarkPlaces).
I mean, did it rain recently in hell ?

Your last screenshot shows how beautiful it can be.
I love this one
http://www.bild.me/bild.php?file=8949540shot00033.jpgI wish Doom 3 had more hellish levels. And not the industrial/base ones.
But that is "Doom"-like. I guess I have to stick to Quake1 then...
The best Doom3 mod, that left my jaw open all the time and had this "Quake" feeling
is "In Hell - Director´s cut" by Doomi.
I guess when I would play this mod together with your extended engine, it will be exactly what I wanted

Could you please try to load up the "In Hell" mod with your engine files ?
Thank you for all your efforts reckless !
Best wishes,
Seven
