shape sequence - custom properties?

[rookyspooky]

At the bottom of the Shape operator is an option to assign shapes based on a custom property index. You can use that to control the order that the shapes are assigned to particles. For example, if you have 5 particles and 5 shapes, you can store their birth ID in a custom float channel with a Custom Property operator, then load that value into the Shape index settings in order to have them receive their shape in the order they're listed in the listbox.

Thanks a bunch! The only thing I noticed, when I add a spawn_node in the birth_event the Birth_id's in the next event are mixed up and the shape sequence is mixed up as well. Otherwise it works great!

What I want is birth_event -> particles with tail(spawned) -> time test -> event 02 = particles swith to letters in sequence ( which works, only without spawn).
