I have some questions about the flight loader callback.
1. If I have a database that uses external refs
I don't always get a callback on all the nodes that are
part of the performer tree.
If I have two external files modelA.flt and modelB.flt.
modelB.flt has an external ref to modelA.flt.
If I model the following database
db
|- base geometry
|
|- external ref to modelA.flt
|
|- external ref to modelA.flt
|
|- external ref to modelB.flt
| |- external ref to modelA.flt
|
|- external ref to modelB.flt
|- external ref to modelA.flt (*)
For all nodes I get callbacks except for the one
marked with (*).
What is the reason that for a second level external
I don't get callbacks for a second instance of the
first level external?
2. The callback function has in it's switch statement
the constant CB_PATH. The Readme file says it is generated
when we use the road or road path in the flight file.
What do I have to model to get a callback with CB_PATH?
Thanks if anybody can answer one of these.
Mario
