I haven’t really messed around with VFX or CFrames all that much. I found this when trying to test out my VFX for a move. I meant for the VFX to be on the floor but the orientation was all messed up.
This is the line of code that I used to emit the particle.
VFX_Event:FireAllClients("CombatEffects", RSStorage.VFX.Weapons[weapon].Critical, char.HumanoidRootPart.CFrame, 3)
