hello,

something is wrong with the second line. any ideas?
basically i want to object merge all selected sop nodes into its own /obj/geo container with the proper naming.
thanks…

selNodes = hou.selectedNodes()
selNodes_children = []for node in selNodes:
    for child in node.children():
        selNodes_children.append(child)geo = hou.node('/obj').createNode('geo')
geo.children()[0].destroy()
objmerge = geo.createNode('object_merge')
#for parm in objmerge.parms():
#    print parmobjmerge.parm('numobj').eval()
objmerge.setParms({'numobj':len(selNodes_children)})
for i in range(len(selNodes_children)):
    objmerge.setParms({'objpath%d'%(i + 1) : selNodes_children[i].path()})

import hou
selNodes = hou.selectedNodes()
selNodes_children = []
for node in selNodes:
    for child in node.children():
        selNodes_children.append(child)

geo = hou.node('/obj').createNode('geo')
if geo.children():
    geo.deleteItems(geo.children())

objmerge = geo.createNode('object_merge')
objmerge.setParms({'numobj':len(selNodes_children)})
for i in range(len(selNodes_children)):
    objmerge.setParms({'objpath%d'%(i + 1) : selNodes_children[i].path()})

Hope it helps

thanks i was impatient and got help from a colleague…
that code works as a shelf tool. any idea how it could work on a button referencing itself into a geo container?

for each selection:

import hou
selected = hou.selectedNodes()
root = hou.node("/obj")
for node in selected:
        merge_name = node.parent().name() + "_" + node.name()
        container = root.createNode("geo", merge_name + "_extracted")
        merge = container.createNode("object_merge", "objm--" + merge_name)
        merge.parm("objpath1").set(node.path())
        merge.parm("xformtype").set("local")
        container.moveToGoodPosition()

each selection into one geo container:

import hou
selected = hou.selectedNodes()
root = hou.node("/obj")
container = root.createNode("geo", "extracted")
merge = container.createNode("object_merge", "objm--")
merge.parm("numobj").set(0)
merge.parm("xformtype").set("local")
for node in selected:
    i = merge.evalParm("numobj") + 1
    current_path = ("objpath"+str(i))
    merge.parm("numobj").set(i)
    merge.parm(current_path).set(node.path())

You need to convert your geo container into a digital asset first and add your code as a function under the scripts tab in TypeProperties. Then add a button and have the button run your function as a callback script.
Please check these docs for more info about digital assets.

yes. but the code searches for selected nodes, not the node where the button lives. like fetching itself and obj merge it…
