So I did a quick search on the forum and all the fog-related topics, but none of them discussed the problem I’m currently facing. I’ve made a map that has worldwide fog in it (added through worldspawn and _fog) and I’m using the default radar fog. The problem is however, that the fog somehow makes all of the brushes transparent, making the FPS drop down to 30-35 fps because all of the brushes can be seen.
Here are a few screenshots:
At first I was wondering if it had anything to do with all the costum textures I’m using, but that would make no sense, especially because they are all .jpg and therefore have no alphachannel.
It is quite annoying and I really like the effects the fog brings. Help anyone?
