Point Sprite Question

Hey I’m messing around with point sprites a bit here, actually really cool function i have it shooting out a ton of little “virus” looking pictures when you touch the screen that bounce and multiple and etc… Most of the PS I’ve been able to manipulate quite easily.

But when the particle or virus dies rather than having it just disappear I’m wondering if there is an easy way to have it fade out compared to just popping out. Is there something I can connect to the particle sop or point sprite to give it this functionality. Or do I need to start playing around with GLSL shaders to get this type of effect?

You can use a Point SOP and the $LIFE variable to change the value of the point scale attribute to scale the particle however you want.
