# How to make particle system animate in different key frames

I have a water spray which sprays particles at a given frame range. In-between there's a break where the spraying stops but after certain frames I want my spray object to spray particles again. How can I do this using the particle system? because currently I only have one frame start and end option. I want the emission to take place between multiple frame ranges.

• Would it be practical for you to have the particles still emit, but turn transparent (invisible) for a certain period of time? Apr 1 at 22:26
• Would be better to have them stop at a certain frame range, but don't mind giving it a try to see how it looks on my animation. How can I go about making them transparent?

Try something like this. I used a sphere as an instanced particle. In the field of the Value Node, enter #frame which will make the value correspond to the current frame number as you animate.
