Hair particles on hair particles I have a dandelion which has a head covered with object hair particles made of an object (seed) which also has particles on it and everything works as expected 


But when I want to use the dandelion as an object to another particle system, seeds don't show up


If you know how can I make it work, help

Then you can tick these options in the Operator Panel:



And press CtrlJ to Join the converted particles to their parent particle object.
