I know this post is really old, and i am using Houdini 13 but I can't seem to find any other help. I've done what the above said to do, but my renders only come out completely black. Not sure what to do…

Much thanks to both of you. Works like a charm

I have an expression on a property node under Uniform Scale: (0.25 + ($LIFE * 50)) and my particles are simulating exactly how I want them too. However, I just changed the Life Expectancy of my particles from 100 to 4. Doing so drastically changed $LIFE thus making my particles scale up uncontrollably. Is there some math that I can do to my Uniform Scale expression to return my particles to the way they were before without having to just tweak the numbers until it looks good again?
