Custom Engine Particle Effects

[robot_rover]

I am making an engine mod and I have everything working, but I would like to make a custom particle effect for my engine. I see that the stock parts all point to .mu files in the FX directory, but I have no idea how to make them. I tried messing around with the particle emitter in Unity, but to no avail. Part tools didn't recognize the emitter and thus didn't make an .mu for it. I have also looked on google, but usually, the only thing that comes up is the Hot Rockets mod. Can anyone tell me how to make custom engine effects, or point me to a forum post that can show me how?  I have no clue. I was thinking it might have to do with using legacy particle effects, given that KSP used legacy animations (at one point?)

(EDIT)

I believe i found it. KSP has a KSP Particle Emitter in the Parttools package.

Wow I look for hours then find the answer minutes after asking the question...
