Just thought I would add.. Iv just managed to loop some of the emitters by following a tutorial I found, but still having problems with emitters that are pre loaded like the one im keen on looping called emitters_05_04 Twisted Tower this emitter has preloaded frames of over 200 when I take the pre load away I cant get it to loop as the full emitter effect or it has a jump in the finnished render, can anyone help with how to loop emitters that need the pre loaded frames to get the full effect.
