Env_fog_controller's FarZ doesnt seem to work correctly
I had a map that I uploaded a while ago and I had this bug present in it, since its a big map, I thought I did something wrong but then I couldnt do anything to fix it. Big visleaf sections seem to just not render even when the FarZ is way past them. I decided to record/make a map to better debug this:

^ This video shows the problem, the env_fog_controller itself just has fog start/end set to 10000 to make it easier to see FarZ which is set to 2000.

^ This video shows that there is a workaround to this, fog start/end remain the same while the FarZ is set to -1, if we then use console to fire ent_fire fog SetFarZ 2000, it works correctly which confuses me why the normal method has issues.
farzfog.zip ^ The map itself was divided into a bunch of 1024x1024x1024 chess patterns with orange/gray dev textures for easier visibility. Consistent on other branches.

From 2 seconds looking into this, the FarZ option in Env_fog_controller also affects how VVIS splits the map. It basically acts same as -radius_override command line option for VVIS.
I don't think there's really anything to be done about this.
