Interruption in FX - "Spray of Water" [ANSWER]

I'm doing a funny skit where we flashback to the stoneage and a little kid wearing a fire helmet (now a very old firefighter) has his back to the camera and peeing on a fire to extinguish it.
The effect worked out. However after a while the stream is interrupted and restarted. I can't figure out how to make sure the stream runs the entire time.
Can anyone give me advice how to adjust the speed/particles/etc?
I have the duration set fine. It just seems to run out of particles and restart.

I'm not sure exactly, because I can stretch the effect as far as I want on the timeline, and it works continuously.
Do you perhaps have two copies of the effect on the timeline,one after the other? How many frames does it go before it stops?
If you have changed any of the default settings, it might be as simple as increasing the Particle : Max slider. Go ahead and boost it way up and see if it makes a difference.

Hi. Actually I did that and it "almost" did it. But there is still a small interruption.
I got the feeling that each effect can have a maximum particle limit of 2500 before it's over. Then it restarts. Depending on how many particles I choose and their life it seems that would make a difference. I just can't find the combination.
Do you want a link so I can show you what I have so far? Maybe it will be apparent to you. Let me know.
(And no, I don't have two copies. I have made that mistake before already and learned my lesson
Thanks for taking the time to reply. I appreciate it.

I made the preset, and did have this problem when I was making it. it was easily fixed by rasing the max particals. Did you perhaps slow down the particals? try speeding them up, or lowering the lifetime.
Also, when I made the preset, i submitted two layers, the partical one you have and a grade object to go over it. for some reason the grade object was rejected, even though i feel it really helped sell the effect. you can download it here if you like: http://homepage.mac.com/sgb4622/filechute/Spray%20of%20Water%20Layer%202.FXpreset_pack
. Make sure the object mask is set to your first layer.
EDIT: just thought of somthing. did you perhaps lower the scale considerably? If you did, try making the particals a little faster

Hi. I did reduce the scale considerably. I had the particles maxed at 2500. I did increase the speed.
I guess I could increase it more however it would not allow the arc needed to make it realistic. I figured reducing the lifetime would make it worse..
That's the only thing I didn't do. I guess I don't have a good understanding of the "physics" of the particles concept. Maybe I should start from scratch.
Thanks, I'll try your preset asap. I definitely appreciate it. I'll let you know how works.

lowering the lifetime will help.

If you take the particle rate and multiply it by the particle lifetime, you will get the particle max required to avoid a break in the effect. Setting the particle max to anything above this number will work fine, anything below it will cause emission to stop briefly.

I think I got it. Now my only last issue is the width of the stream. The more I reduce the scale.. The bigger my "break" issue. Increasing speed helps. Any other ideas?

not sure if this will work, but try raising the scale and then making the emitter box smaller.

I'll try it. However I"m using an emitter point.

I'm still working on it. BUT I wanted to say your effect makes it look much more realistic. It's sharp.
