FumeFX - How does one create a seamless loop of fire?
show user profile  Spear Chuck
Animating in Max can be seamless when the (100 frame animation) starting keyframe is set at -100 and ending keyframe is at 100.

Using FumeFX is frustrating me becaue I can't seam to create a seamless loop which is undetectable as it starts over. Does anyone have a solution or a Youtube tut I may study?

Ive not done this for ages but if I remember right this should work .

render out the fire and then import it into a video editing program you then blend/fade the end of the animation on to the start of the animation. so take say the last 50 frames from the animatioin and mix them onto the start and fade these frames out that way you hide the end and start of the loop. :)

hm.... yea I'm not sure that it's going to be easy to get a seamless loop with a particle simulation, regardless of what package it is (I could be wrong though? I'm not a particle guy). Your best bet is to probably render out more frames than you need, and then find the best frame range to blend and mask around until you get a loop point. I doubt you will get a good loop natively from most particles simulations. They are designed not to loop or have much of a noticeable pattern

You may be able to get away with just a slow fade, but you'll probably want to make an animated mask to help out with the fading. Fire travels upwards, so having a mask that travels upwards can help, a soft animated bezier curve or even maybe just an animated ramp. Fortunately, fire is very random looking, so it's probably going to be easy to get a fade going that isn't noticeable, maybe even without masking.

I've done this in a pinch once, had to use footage of fire that was not long enough, and had to make a loop out of it. It's not to difficult. -

I appriciate the help, I'll try adding some frames to kick start the ignition.

I have other objects on the move to at the get go so adding few frames in front adduh do it. Then do the blending.

Thanks dudes

best way to loop is to render your simulation the following :

let's say you want 200 frames looped :

frame 0: particles start emitting (so you start with a blank frame)
frame 200: particles stop emitting

set the lifespan of the particles to let's say 100 and render out till frame 300.
Then in post you make the composition length 200 and duplicate the layer and set the inpoint of the the second layer to -200 so you got 100 frames overlap.

You got yourself a seamless loop.

The skip is barely perceptable

I'm to tired tonight to change the height
How do I cut off the excess at the top using AF?

lol, barely noticeable ? There's a blank frame inbetween...
