How to copy&reference all the param using python

[Hiro11]

import hou
import pprint


node = hou.node('/obj/geo1/subnet2/TestNode')

number = 5


parm_tuple = node.parmTuples()[number]


name = [parm.name() for parm in parm_tuple]
group = node.parmTemplateGroup()
parm_template = group.entriesWithoutFolders()[number]

myIndex = group.containingFolderIndices(parm_template)
folder = group.entryAtIndices(myIndex)


ContFolder = group.containingFolder(parm_template) 


name = ContFolder.name()
label = ContFolder.label()



node = hou.node('/obj/geo1/subnet2')


group = node.parmTemplateGroup()


folder = hou.FolderParmTemplate(name, label)
folder.addParmTemplate(parm_template)
group.append(folder)



node.setParmTemplateGroup(group)

I am not a python guy, and I'm stuck and need some help.

What I want to do is, I want to make a custom HDA that has a node(ex.Mantra) inside, and I want to copy all the parm(+folders) in the Mantra Node,and paste it in the HDA parameter.

Also I want to reference it each.

 

I tried and figured out how to copy the parm and folder,but when I do this to all the parm,it will make a lot of folder with the same name...

 

Is there any good way to do this? I want do it with python.

 

Thanks,

Hiro

       pprint.pprint(name)
       
       reference = (child_path + "/" + name.name())
       handler = (parent_path + "/"  + name.name())
       channel = ('ch' + '(\"../' + name.name() + '\")')

       if name == node.parms()[i]:
          name.setExpression(channel)

 
reference()

I think I got it.

There is some trouble sometimes.(Dont know why)But,needs time to figure out why it sometimes gets an error...

Don't know if this is of interest to you, but there is actually already a feature built into Houdini that does that:

 

 

Not sure if you can refresh it though via Python dynamically. Here's an old thread about it https://www.sidefx.com/forum/topic/34941/?page=1#post-290083.

Hi,Sorry for the late reply.

 

I did not know this.I think I will do it this way.I am so happy to know this!!

I did finish the python way,but its not a very good way I think... Also I am not a python guy,,,(cry)

 

The refresh with python, It would be best to do it,but I cant find anyway to,,,So I think I will do it by hand.

Thanks,

Hiro

No problem, you can also look into how the TOP>hdaprocessor node does it. (You can select an .hda and it then rebuilds the parms in the "HDA Parameters" Tab).
