Performance seems unimpacted, tested locally, should work fine.
randConeEmit - Default value 0 (no cone emission), similar to
randomInitalVelocityOffsetMaxRadius, but a little less random effect
appearance in-game. Forces a mirrored emission to ensure symmetric
plume appearance.
xyForce - default value 1, multiplicatively damps or grows horizontal
(perpendicular to exhaust velocity) speed.
zForce - default value 1 multiplicatively damps or grows vertical
(parallel to exhaust velocity) speed.
