need help with particle generator

I have created a particle generator with an anim brush set to loop. Unfortunately, the particles are not looping right. One frame is randomly missing.
I would like to upload a tvpp file, the effect.bin and the anim brush. How can I do this here in the forum? It says "The extension tvpp is not allowed".
If someone could take a look at the files, I would be very thankful.

zip them together and you should be able to post the zipped file as attachement.

maybe it's a matter of frame-rate ?
try to load your animbrush as a new project, and set the particule shape /source to this new project.
(take care the main project + the particule source project are set at the same frame-rate)

edit : bug confirmed;
my source test was 9 drawings timed in 2's = 18 frames,
when the particule applied, some of the source drawings are in one's (4, 6, 9, 3, 6, ...)
so it looks like periodicaly, one frame is skipped. :o

oh no, so you mean it is a bug? I really need this right now. :?
I guess there is no need to upload my files then...

I always used 24fps and have 5 drawing in the anim brush. On some particles Nr.3 is skipped and on some Nr.5 etc.

edit: It doesn't seem to work properly with any "Shape-> Animation" setting, except for random of course :|
If anyone knows a workaround please let me know.

Try a layer as source instead of a brush?

Well, bad news that you need this to work right now, but good news is that the bug was discovered . Thankfully the trusty TVP Dev. team will probably have it fixed by the next update.

I always have mixed feeling when I discover a bug :D

When I choose "project list"-> untitled the same thing is happening. Some frames get randomly lost.

Well, I think I will animate the particles in one place and then use the key framer to move them.

Here's a button/script combo called "StepDraw" which lets you position sequential frames from an animbrush by hand, to layer frames, advancing one frame at a time. It can be used as a kind of "hand-made" particle generator.

It gives you more frame by frame placement control than the OPTION in Preferences/General - "Stroke Animator" check box which Changes the current frame during drawing when the CTRL key is held down.

StepDraw.tvpx file here with instructions for use.

hi there,

Can someone post a project + a particle to show us the bug ?

Here are the files:

With the new update (10.5.7) it looks a lot better but the bug remains, I think.

I set the frame rate to 24. Now some particles loop correctly and some hold one (random ?) drawing for two frames.
