  • Particular – Custom particles disappearing

    Posted by Jeffrey Parsons on October 30, 2009 at 6:08 pm

    I run into this problem all the time and have never found a cure, I just work around it. I’m sick of it.

    In this case, I have a spinning 3d coin movie with alpha that I want to use as a custom particle.

    I set up the comp, add the coin layer (which is a nested comp), set Particular to use the coin as a custom particle, set “Random – Loop” and animate so that the coins are exploding out from a logo. Everything looks great, but looking closely one can see that some of the coins disappear then re-appear a couple frames later.

    I have no blank frames in the coin comp I am using for the custom particle. It’s just a coin spinning one revolution.

    I can’t figure out why some of the particle coins pop on and off like that. When particle type is set to “sphere” I don’t get that problem.

    Anyone?

    What is your current solution for this? By knowing this, we may be able to reverse-engineer a problem.

    Best,

    What makes you explode?

    I can’t recreate your problem. My guess is that it’s some problem in the nested composition or some sort of a mixed frame rate issue (what frame rate are the compositions/footage?)

    Thanks all for the responses. I tried to recreate the problem at home, as I am not currently able to access the project I was having problem with… but of course now, it’s working fine. I will take a look at that other project on Monday and see where I may be making a mistake, though at the moment I have no idea.

    I have had this same problem — I used a Tree as a custom particle to make a forrest and the trees popped off even with a very long particle life — I seem to remember reading that Peder (head honcho at Trapcode) was aware of this problem and there are postings on this subject on the Trapcode Forum within Creative Cow…

    Also, I’m guessing (only guessing) that it was fixed in the new version of Particular (which I don’t have yet — so I’m not sure about that)…

    Thank you for responding to my post. How I ended up solving the problem was using my After Effects 6.5 version with a Trapcode Particular 1.0.1 version. For some reason the problem doesn’t happen in those versions.

    It’s not really a solution, but I just make the precomp with the particle (coin, or whatever) very very long. Particular still drops a few particles, but far less often.

    I solve this problem by changing the random seed number.

    In the composition where you have your sprites, under composition settings- advanced- activate “preserve frame rate when nested…”

    This did the trick for me.
