Particle system not . . showing up

highly doubt i will get help with this, but i am DESPERATE.

i am making an avatar and i am currently trying to give it a particle system,
basically a gun. if the hand is open, its meant to shoot, if not open, no shooting.

. . problem, it does NOT play or show.
it does play if i select it within unity and PLAY it, but it doesnt play in play mode, or ingame.

i mainly use quest since my pc is unable to handle PC VR as of right now, so i am confused if this is just a quest issue or not.

(i am also using VRCfury for my avatars if that .. helps.)

please tell me if i should add more detail, like. specify of what you want to know so i can tell you.

Hello, can you share how you do your animation to trigger the on and off state of your particules system ? Do you have a manual animator in the FX Layer, a seperate one you merge with VRCFury, stuff like that ?

i have been told that vrcfury does NOT fair well with particle animation triggers, so . . i decided to watch a liindy video of how to do it, i THOUGHT i did everything right, but for some odd reason it STILL doesnt work. i used the normal . . like. animator and adjusted stuff in the FX layer, and made the shooting toggles . .

still didnt really work, unfortunately . . :[
(sorry if this doesnt tell you much im a little slow)
