Niagara blood spurt system appearing black on IOS, working fine (red) on MAC and WINDOWS

Hello, I am using a Niagara particle system from the FXVille Blood VFX pack downloaded from the marketplace. Its triggered when the enemy AI is hit by bullets, and creates a nice bloodspurt. Its deep red and pretty reflective. This works fine on Windows and Mac, but when I launch the game to IOS the spurt turns black. It maintains its reflectiveness, and functions perfectly, but is jetblack. I am happy to post any more info needed to answer this question, I am just not sure what that would be. Is this an export setting? Or a bug with the niagara? Could it just be the asset I downloaded? Thanks in advance!
