i use refraction to make my effect can get the distortion like left side in the preview in Niagara .
but the problem is when i put i in the game side ,the refraction will become very strong and that is unexpected,
i think it is affect by distance between my camera and particles , when i set my camera very close to my particle the refraction value is what i want .
any one konw any way i can get the same result like left side whatever my camera in any place ?
