Particles winking in and out of existence? (particular)
by Robert Storm on May 2, 2008 at 4:01:56 am

So I picked up a copy of Trapcode's Particular, and was following Andrew Kramer's excellent tutorial on creating a bloodstream, when I hit a snag.
Everything works fine, except that some particles just...disappear for a frame. Not the same frame every time, some disappear on the same frame, others on other frames.

Here's an example (it's obviously not done yet):

See how just after the second name is developed, the cells kinda...disappear for a frame or two? (You might have to scrub through)

Any ideas on what this is or how to fix it?

Dude - I'm having this same problem. I posted something on it just two days ago.

ahh that looked sweet dude!
Well, I think I figured mine out- I'm not sure why, but if you just restart the program, and then don't scrub through the timeline at all before you render, they all appear.
Weird...but I guess it works =

The reason this is happening is due to the After Effects image cache. Particular doesn't update the image cache unless it's forced to.

The fix is go to Edit>Purge>Image Caches and re-preview or render.

I think Andrew discussed this in one of the tutorials, but it can be missed...

Unless of course, it's something else...
