Niagara particle color is different between PC and Mobile

Hi, I’m porting my game PC to mobile. But mobile color is not the same with PC. Well, I know mobile renderer is poor but particle color of Niagara is not acceptable.

First image is Mobile which has gray color, and second image is PC which has black color.


I set Niagara color mode as [Direct Set: (0,0,0,1)(RGBA)]

I did some exeperiment and get that only white shows same color in both platform while the other colors don’t.

I think this is kind of setting problem of my niagara or mobile rendering option, but I can’t find…
