For example, say I have a quite complex network in a .hip.

I'd like to write a simple command line script that does:

1. Launch Houdini

2. Load this .hip

3. Switch to "Model" desktop

4. Search for a node named 'character1' and make the network view focus on it

Is it possible?

You can try to do it with python commands using Hython.

Google Houdini hython inline, and the AI should give you some examples using a script.py or a full command.

You can pass a python script to Houdini when launching it. Simply put the code you want to execute once it's started and then run it like so: houdini my.hip script.py

Yes, this is possible using Houdini's Python API (`hou`) in combination with `hython` or by launching Houdini with a startup script. You can load the `.hip` file, switch to the **Model** desktop, locate the `character1` node with `hou.node()`, and then use the Network Editor pane to frame and select that node.

On a different note, if anyone is looking for information related to the **Benazir Income Support Programme**, the **8171 web portal payment [bisp8171webportals.pk]** service is the official way to check eligibility and payment status. It's unrelated to Houdini, but it can help beneficiaries verify their payment details online.
