How to change Textport's current node?

When I open Textport, the prompt says "Director":



However when I open Textport from other people's hip files, the prompt says the current node:



Why is it and how could I change the current node of Textport? Is there a command similar to Unix's cd?

Texport is like a command prompt and you can navigate through a Houdini scene as if you were in an OS's file system. opcd (or opcf) to change directory (node); opls to list the contents of the current directory, so on so forth.

You don't need special commands to do this. Many transition commands already have aliasing.

I don't think the alias is default.



But yeah it might be wise to add these.

those aliases are the default ones, but you can check whether you see them set in your session

however I've never seen Textport open saying Director ->
this is the Textport in my vanilla install

Houdini might be launched incorrectly. There might be conflicts in the path, or the houdini environment isn't being initialized.

The weird thing is that when I open other people's hip it works as you showed. But my own hip, even an empty one, always causes the textport to say "Director ->".

Ok, I found the reason. It's extremely weird tho.

I have this empty 123.py in my scriptsfolder:

import hou

Remove it fixes this issue. I'm not kidding, this empty 123.py even breaks the built-in aliases.

That's the init script for Houdini, so that checks out. If you have 123.py in your path it will take precedence over the built in one--so you can customize startup. Normally your script looks for the built in one and executes it first though. An empty script won't though.

Ah, you're correct.

For the reference, the correct way to do this seems to be:


with open(hou.text.expandString("$HFS/houdini/scripts/123.cmd")) as f:
    hou.hscript(f.read())

In 123.py. This will run the built-in 123.cmd, which sets up the aliases and the textport's prompt.
