Before downloading this fix. You must know that you need to have the Official SA_DirectX 3.0.
I have edited the original timecyc of SA_DirectX 3.0 in order to fix the bug of the interiors. This edit preserves intact the graphic properties of the timecyc that Makarus made for SA_DirectX 3.0. The only change I made is related to the environment properties, in the "FOG" section. I have cloned this fix in all cycles and climates of the game.
Apparently not everyone has this problem, but people who use mods that increase the drawing distance know that this bug exists and it is very annoying. This fix will be very useful for them.
