While rendering a movie my niagara fire appeared fine while there was severe motion blur (frames mixing and blending) in the media player chroma key png sequence projected on a plane. I found that the culprit was MOTION BLUR parameter of the CAMERA ACTOR which I turned to zero. This completely removed the motion blur from my chroma sequence and it became sharp at its orignal 24fps png sequence. But the niagara fire went nuts and looked smeary and streaky. Is there a way to tweak the niagara fire frame rate (not its speed but fps) same as my level sequence frame rate so the fire looks prominent at 24 or 30 fps sequence rendering. When I bring the motion blur of the camera actor back to .03 it fixes the rendering of the fire BUT again badly blurs overlaps frames of my chroma sequence which means I cannot use motion blur. For the record my png sequence and se level sequence are all properly set to 24. I bumped up to 30 but the fire still goes smeary. Thanks for the help in advance
