I've created a grassy meadow in Blender 2.79 using a hair particle system with interpolated children. It looks great except that the hair strands are all exactly the same length. I know I can make a certain percentage of the children be a different length, but that still only gives me a mixture of 2 lengths. I really, really need a way to slightly randomize the strand lengths so the field doesn't look like it was lab-grown. There doesn't seem to be any way to do this. Am I wrong?
