Using Colissions For Multiple Hair Systems

[pyrokinesis]

Hello friends,
I am using multiple hair systems, and would like to use the same hair constraints(colission spheres) for multiple hair systems. I have tried making connections in the relationshipo editor, but do not see them there. I also tried to go into the hypergraph to make the connections manually. I found that I could switch the connections from one system to another, but not add to current hair system.

Example:
I want to take the colission spheres from one character, duplicate them and use them for another character.

There seems to be an array attribute called outPin[0], which allows me to connect to the hairSystem, but the array attribute inputHairPin[0], does not let me add members, only replaces the [0] indicie.

How do I add array inputs to the hair system? or simply duplicate my colissions to use on another hair system. I know there is a simple script, or a node. Im just missing something. Any help would be appreciated.

Currently hair systems cannot share hair constraints. However you could create new collide constraints for the second system then parent them(preserve position OFF) to the the original constraints and hide them.

Actually reading your question again I see that you want to duplicate the setup to another system, rather than sharing the same constaints between two systems.

The constraint is assigned to particular follicles when you create it. The list of follicle ids is an array attribute on the constraint node. You could duplicate your setup to another system using a script. If you need to do it a lot or if you have a large number of constraints it might be worth writing.
