Siberia Tank Fog Bug

[shoober420]

does anyone else have this issue when playing Siberia with the tank on the bridge and fog rendering incorrectly at a certain distance and angle?



im using the sofplus patch 20140531 on gog platinum edition release

In a nutshell. I think it's a map design flaw caused by two different fog (and different fog settings) region colliding each other.

If your PC is fast enough. This can be fixed with cvar r_novis 1

when enabling r_novis 1, this breaks the fog rendering on my machine, even with default config. it does appear to fix the tank though, but no fog is rendered

[Acadie]

Yeah, you're right. I was testing it in a specific location that wasn't happening. So far, I tried tinkering with cvars but I can't get a workaround without the break from r_novis.

i noticed gl_fogmode is broken unless you use value 0. all the other fog options are borked and just change the color of the textures. are you using SoFplus 2022 from the community patch? im using the old SoFplus 2014 release from the website atm

gl_fogmode is a beta left over used to be for high/low quality setting in the menu page but it is true that 1 (low quality) is broken. The other two value are just for debugging.

i tried using QeffectsGL and dgVoodoo2 Glide wrapper but they do not fix this bug

[Acadie]

It's from the game that is broken so there's no solution to fix.

the closest i got was messing with gl_fogend and gl_fogstart, but it still happens at a different distance. i imagine if they bundled a fixed modded Siberia in the patch, Activision wouldnt be too happy. what if they bundled a fixed Siberia in the GOG release?

Coincidentally, Raven did release the source map file for the three Sib levels. Thus, it is possible to fix the tank bug ourself. There's a bigger bug with the second Sib level where the female enemies can crash the game when your stealth meter is too high.
