1. Decompile your mp map.

2. Find the map that has your weather and decompile it's sbsp.

3. Open your maps bsp meta in h2guerilla.

4. Open the map with weather's bsp in guerilla as well.

5. Find the weather pallette in the map with weather's bsp.
6. Click Copy.

7. Go to your maps bsp meta and find the weather pallette.
8. Your map shouldn't have a number next to the weather pallette. So click the insert button.

9. Now you should have the number 0 next to it. Moving up a bit, you should find the Visual Clusters/Meshes.
10. Open the Visual Clusters/Meshes. In each chunk there is a index to the weather palette set to -1. You want to go through each chunk changing them from -1 to 0. So make sure all the chunks have a weather index of 0. (Coagulation has 47 chunks, so all of them should be set to 0).


11. Save changes.
12. Rebuild map with the new bsp meta. (If you don't understand this. Just rebuild your map with the same scenario you decompiled from it.)
13. Ftp and check to see if the weather was added.
DONE!
