Hi, I'm not sure that's what you really need to do but I've been using and manipulating hierachies of custom properties for a long time now. for this, I use an addon I first published nearly 10 years ago: http://hnegadi.myftp.org/resources.html
The core is a quick and dirty vbscrip plugin but it still does what I need
from so I never got the chance to do a complete refactor.
Basically the AddProp xsi built in custom command allows you to create any
custom property nested underneath the object ( including another custom
property ) of your choice.
Here is an quik and dirty example:
AddProp("Custom_parameter_list", "Scene_Root", siDefaultPropagation, "cp0" );
AddProp("TextProp", "Scene_Root", siDefaultPropagation, "text0" );
SetValue("text0.Text", "there she goes again" );
SIAddCustomParameter("cp0", "Param0", siDouble, 1 );
SIAddCustomParameter("cp0", "Param1", siDouble, 2 );
AddProp("Custom_parameter_list", "cp0", siDefaultPropagation, "cp1" );
SIAddCustomParameter("cp0.cp1", "Param2", siBool, true );
SIAddCustomParameter("cp0.cp1", "Param3", siBool, false );
AddProp("Annotation", "Scene_Root", siDefaultPropagation );
SetValue("preferences.scripting.language", "JScript" );
If you install xporc plugins, you'll find menu items that allows you to
replicate and move custom properties hierachies, which means duplicate and
reparent in xsi classic objects terminology.
Unfortunately, I wrote these ages ago and the commands are selection based
and don't take input arguments.
Since XSI doesn't support duplicating nested custom propertis, the
workaround consists in replicating recursively the hierarchy you want to
duplicate: Store and recreate the custom props and copy their params and
values.
I'm not sure any animation or expression source replication are supported
though.
Attached are the vbs functions I use in xproc to "replicate" hierarchies of
custom properties ( I removed the vbs extention so google would allow me to
send the attachement ).
Hope this helps.
