Don’t use areaportals on windows… Seriously. Keep your areaportals to doors in CLOSED-IN ROOMS. And SPARINGLY. You can overuse these. or nodraw textures on one side of them. You don’t want someone to see inside? Use a opaque texture and not a transparent one.
That map is pretty much what NOT to do. There’s overlays clear in the void (at least 20 of them I’ve deleted) One light in the void leaking to Cultulu and it hurts the God’s eyes, touching area portals and, nodraws all over the place where it’s not necessary… It’s a trainwreck.
I just started mapping and even I understand you don’t do things like this.
Seriously. Please don’t do this kind of stuff when you start learning how to map. It makes my eyes bleed.
