It seems that when using the runPythonScript command in a .pz2 file it will run the called python script twice.  Quick example:

The .pz2 file contains:

{
version
 {
 number 6
 }
runPythonScript ":Runtime:Python:poserScripts:Test.py"
}

The Test.py program contains:

print "Hello World"

When running this, it will print "Hello World" twice.  If I invoke the script from material file (e.g. test.mt5), it runs correctly and prints only once.  Any ideas on how to get the runPythonScript command to execute only once from a .PZ2?

The script is called only once from a pz2 file, if you put the Python call in the second part of the pose.

Use the following as pz2:

{
    version
    {
        number 6
    }
}
{
    version
    {
        number 6
        runPythonScript ":Runtime:Python:poserScripts:Test.py"
    }
}

}
{
    version
    {
        number 6
        runPythonScript ":Runtime:Python:poserScripts:Test.py"
    }
}

Many thanks.  That works perfectly.  How in the heck did you ever figure that one out?  Anyways, thanks again

Actually, it was just luck. I tried a few things to see whether it will have any influence on this behavior.

I just wonder if this is intended behavior or a Poser bug. It looks as if poses are always applied twice, readScript calls in a pose are also executed twice.

Thanks a lot !!!!

I managed to avoid this with adding a 'trigger' on the UNIVERSE actor.

If there was no trigger, then the script must be launched.
If there was the trigger, the script removed it and exit with doing the rest of the script.

But this way is MUCH better !
