NIAGARA create random size with curve?

Hi,

I want my sprites to have a random size, BUT i’d like to drive the randomness from a curve.
So my size goes from 1-10, but i want 90% of my particles to be a size between 1-5 and 10% of my particles to have a size of 5-10 if that makes any sense.

Just starting out with niagara so it might be super obvious ^^

thanks!

“Float from curve” is what you want.

Then replace CurveIndex with your random numbers.

Well this should do it, but it just makes all my sprites small… though i multiply it with a curve that goes from 1-8 so it should only increase size?
