It has galmap section, it has 3 presets low/mid/high which is loaded when u select in-game mid/low/high. So "high" one has 0.0 multiplier for dust, which effectively removes it. In horizons i did there like 0.0001 so dust cannot be complete removed.are you saying that just updating an xml file restores the clouds ???
Can you post the updates? I have never done this.
Galmap section also does skybox. Same config for both.
