[Step 0] Have the Scatterer mod by BlackRock.

You can get it from: https://github.com/LGhassen/Scatterer/releases

[Step 1] - Choose a quality:

High - For 4K players, and beefy machines. (If you get banding then use the medium one instead)

Medium - Recommended for most users.

Low - For older laptops, or people with very little memory.

[Step 2] - Pick a colour.

Look in the 'Preview Images' folder and pick one that you like.

[Step 3] Installation:

Place the file 'Sun.CFG' and the folder 'Sun' to your ..\GameData\scatterer\config\Sunflares\ 

Scatter actually already comes with these two, so just overwrite, or backup first then overwrite them.
