Pleeeease! scaling particles

#1

Hi guys
I want to spawn specific number of particles on surface of an object, from left to right.
The particles appear suddenly but I want them to scale from 0% to 100% and not more than 100%.
I tested some ways but resulted nothing!

I hope you got it what I meant.

Really thanks for your precious help.

Is it really that hard that nobody doesn’t know?!

Add a scale operator, animate it’s scale factor, done.

yes animate scale operator from 0 to 100. Over a set amount of keys on the timeline.
also make sure scale type is set to absolute and timing is set to particle age…

You can use a birth texture with an animated gradient ramp to birth your particles.

happy new year.
