Removing shopnet attribute in bulk?

[archz2]

I'm trying to import an fbx model with embedded textures but the textures don't show up in the render. 

They get hidden in render because of this shop material attribute that I have to delete for each and every piece of the watch.

 

Is there an automated way to delete this attribute instead of entering the node for every piece inside the wristwatch?

I converted the embedded materials by using ODtools.

Here's the project file.

1. Create an attribdelete with required parameters

2. Windows > Python Source Editor

selected_nodes = hou.selectedNodes()
source_node = selected_nodes[0]

subnet_path = "/obj/Hublot_King_Power_F1___Watch_fbx"
subnet = hou.node(subnet_path)
file_nodes = [n for n in subnet.allSubChildren() if n.type().name() == "file"]

for file_node in file_nodes:
    parent = file_node.parent()
    copied_node = source_node.copyTo(parent)

    outputs = file_node.outputs()
    copied_node.setInput(0, file_node)

3. Select attribdelete to copy to

4. Appy script

It will copy-paste selected node into each node in Hublot_King_Power_F1___Watch_fbx subnetwork and attach it to file* node

Thank you!! Wow! This worked quite well! Is it also possible to set the display flag to attribdelete inside each of the parts in bulk too?

Another thing. 
Is there a direct way to select materials of each piece rather than checking what material is applied to it in the render tab by selecting the obj node and then going to the matnet and then searching for the name amongst 50 materials used in the project, and then clicking the material node?

 

If I click on this button on the right side of material it opens a window containing list of all materials inside the model. Doesn't open the directly the material network of the material applied to the geometry piece.

 

 

 

 

Jump to operator button right next to it only shows this panel.

attribdelete is set as render node already

not sure I understand what this issue is, jump to operator shows exact material applied to the node

Ok. Right. I ran the script again and found it was that indeed. My bad.

Also...while importing the fbx, I came across a better import option that places materials inside the existing matnet instead of creating a new one inside OBJ network.

 

It also creates all parts directly at the OBJ level, rather than nesting everything inside a subnet (which is what my earlier method was doing).

Would it be possible for you to tweak your Python script to work with this setup instead?

Here's the updated project file.

Also, I had a broader question.. Is there a no-code way to achieve something like this in Houdini?

Right now, this approach requires knowing Python, remembering the logic, and executing it each time. Is saving these scripts in a file the standard workflow, or is there a more efficient way (like shelf tools, digital assets, or something else) that you’d recommend?

Wrap new nodes into one subnetwork and use the logic as before.

Alembic, USD...

Save script as a shelf tool. Improve script to be able to select "subnet_path", fully create "attribdelete" instead of copy-paste. 

Google Python examples, you will find close enough to this tasks.
