Hi;
I would like my particle source emits just 100 particles at first frame , but the problem is, the emitter creates particles in each frame continuously…
How could I create just 100 particles once at first frame?

Thanks for helping.
:roll:

The particle system default to continuous emission. Set Continuous Activation to 0 to turn it off, then set Impulse Activation to an expression.

This will only emit particles on frame #1.
$FF == 1

Other expressions are also possible like.
$FF < 12
Will emit particles for the first 12 frames.

Thank you Enivob , but I can't find “ Continuous Activation” parameter…! :?

It is under the Birth TAB. Look for the green field in my example file. It is right under that.
