Here is a smaller Sparkle boost for those who think the default one is cool but has too much sparkles. :D

Bonus: I recommend using the Gold Rush (Alpha) boost sound effects with this one, it fits well in my opinion. (Not included).

If you're interested, check my tutorial on reddit (you just need to go at the end of the post to download the file) : https://www.reddit.com/r/RocketLeagueMods/comments/5jxw5a/tutorial_changereplace_boosts_sounds/

Instructions:

1) Download and configure uMod for Rocket league if you don't have that software yet.
2) Open uMod
3) Open Rocket league
4) Extracted and drop the .dds file included in the .rar archive into uMod.
5) Done.

You will have to do this everytime you restart the game if you want the mod.
