Hi,
you are right, you will need some scripting to create custom actions and component to enable playmaker and corgi to work together.
it's not trivial and usually, this is something initiated by the third party, have you contacted them? you can cc me to your mail, usually, I give them a head start and a couple of examples on custom actions and then playmaker support becomes available by the third party developer themselves which is the ideal situation, unfortunatly, we can not support every third parties...
Let me know how it goes,
Bye,
Jean
