I would like to know if there is a "distance" byeond wich particular doesn't display particles ? I'm trying to add particle effects on a 3d rendered sequence, particular seems to be the way for me, but I encounter a problem with distance (I think it's the problem) : when in motion preview, particles display, but once fully rendered, nothing. It seems that when the camera moves closer particles show. I thought I couls solve the problem with bigger particles, but particular seems to be limited to maximum 1000 pixel.
Any clue ? Any help would be fine. Otherwise I'll have to do it with another particle soft, but particular seems so fine.
