Hi,
When I set up a multi-phase ice-node according to the specifications set on
the webpage linked below in_ctxt.GetEvaluationPhaseIndex( ); returns -1 and
I naturally none of the phase switch parts get executed.
http://download.autodesk.com/global/docs/softimage2013/en_us/sdkguide/index.html?url=files/cus_icenodes_MultiPhaseCustomICENode.htm,topicNumber=d30e19848
Below is a simplified version of my SubmitEvaluationPhaseInfo and Evaluate
callbacks.
If you run it, this is the output:
# INFO : Reached beginning of Evaluate callback.
# INFO : -1
# INFO : Reached multi-threaded part of Evaluate callback
And that repeated for every thread.
So the part before the phase switch and after is being evaluated, but the
part inside of it isn't because ULONG nPhase =
in_ctxt.GetEvaluationPhaseIndex( ); apparently returns -1.
I've gone over everything 10 times and in my eyes everything is set up
correctly, but clearly I'm making a mistake somewhere.
I would really appreciate it if somebody experienced would take a look.
I've also attached the entire c++ file.
Thank you so much guys.
