I would like to create multiple child records once a parent record has been created via process builder. When I try to create a new record, I start the process with the parent object, I do not have an option to create a record on the child object. The only avaiable object from the same app is the parent of the parent object. 

I'm assuming the relationships I have in place may be the issue? 

Is there a cap on objects that are available to create a record with in Process Builder?
