copy/paste Looping through sop to sop

[cloudfx]

Hi all,

I got a lot of sop networks (about 300) in my obj network because I imported fragment geometry from 3dsmax.

I am trying to create a script that could open into each sop network and copy everything,

and paste it into one single sop network(Master Sop Merge).

Can anybody show a good example of this kind of work around??

Thanks a lot!

You could create a smart bundle like

/obj/Sphere*_geo/what_ever_the_last_sop_is_called

and object merge it in to your master object

Maybe the /obj/Sphere*/what_ever_the_last_sop_is_called works directly in the object merge, too.

You will basically want to use hou.copyNodesTo for this. This function takes a list of node objects and moves them to a new location.

You could do something like this:

I can't guarantee it works because I don't have Houdini open but it should

obj = hou.node('/obj')
# Get all the geo nodes that have the correct name.
objchildren = [child for child in obj.children()
				 if child.childTypeCategory() == hou.sopNodeTypeCategory()
					 and child.name().find('Sphere') is not -1]
# Create a new container.
container = obj.createNode('geo', 'container')
# Destroy any children.
for child in container.children():
	child.destroy()
# Create the merge sop.
merge = container.createNode('merge')


for object in objchildren():
	# Get all the sop nodes in the geo object.
	sops = object.children()
	# Find the display node and set a comment to keep track of it.
	displaynode = object.displayNode()
	displaynode.setComment('DISPLAY')
	# Copy all the sops to the new container.
	newnodes = hou.copyNodesTo(sops, container)
	# Find the node that was the display sop in the copied nodes, connect it to the merge and clear the comment.
	for node in newnodes:
		if node.comment() == 'DISPLAY'):
			merge.setNextInput(node)
			node.setComment('')
	# Destroy the object.
	object.destroy()
# Layout all the children in the container.
container.layoutChildren()

What do you mean by a smart bundle?

I never used it. Can you tell me how do I use it??

Thanks!!

Thanks for writing a code!

Should I just open a python shell and type the line one by one?

I never used python shell in houdini.

Only experience that I have with script is Max Script in 3dsMax..

Thanks a lot!

Smart bundles

Normally you define the contents of bundles by dragging nodes onto the bundle in the bundle list pane. However, you can also define smart bundles. These are like smart playlists in iTunes: they automatically include all nodes that match a pattern you define.

But it seems smart bundles are still auto convert to bundles upon close of Houdini

do you really need to script it?

or you just want to merge all fragments to one node

there is a combine button in the modify shelf

but if this is a scripting exercise, please ignore my post
