Technical Discussion » Python Interactive Viewer State Handle problem / question

I'm trying to learn python states and I am building a small tool, so far it looks something like in the screenshot.

I have a problem I stumbled upon accidentally: if hit ' on the keyboard (which apparently is the shortcut for handle detachment) the handle detaches permanently. The tool will not work again, unless I copy the HDA.

I guess I should ask: is there a way to disable detachment for this handle? Or maybe: is there a better way to build this handle in the viewer states, like using a gadget or something (I would like the handle thickness to match the white line)?

Hello everyone, i have just finished writting my first article, it explain in detail how to set up your Visual Studio Code so you have full intelliSense for Python in Houdini, i think it can be usefull for a lot of people so i've put my heart to it •ᴗ•

You can check it just right here : https://pakreht.com/houdini/configure-vscode-for-python/ [pakreht.com]

If you follow throught you should end up with something like this :


Don't hesitate to give me feedback and ask for clarifications on some aspects ಠ‿<

Just found this. Set everything up, including the stub linked on the blog. I'm not sure it works correctly. The code looks nothing like in your gif, and I still get this 'any'. Can you give any hints?

Where could I find all the settings and their functionality that I can use here?
I'm browsing the docs but going in circles with no info.

Technical Discussion » Python Interactive Viewer State Handle orientation problem

I'm trying to build a python states interactive handle and I want to orient a handle to the normal of different primitives. However I don't understand how to correctly orient the handle. In the viewport it appears correct but the values extracted from the handle are not correct. For example in this image the RY of the gives weird values:
Image Not Found

Basically here when I rotate RY in the viewport the actual value from the handle is RZ, or RX -depending on the normal value. It's like there is a different, internal orientation of the handle.

You should probably submit a bug report on the main website. I was able to get that scene working by manually installing the required HDA that the error is talking about.

Those HDAs seem to be located in $HFS\packages\viewer_state_demo\otls, simply install them locally inside the HIP.

Thank you very much! I'll try your workaround.

Not a single example file works from this folder. I have tried opening them in Houdini 20.5.578 Py3.11
Most of them have errors on open. Is there something I am doing wrong?

I am having the same issue even in H20.5, everytime you open the external editor you need to close the file in VSCode to prevent Houdini from crash!

did you use -w like I suggested?

Is this the only solution? Having to close the file and reopen constantly is no fun...

I'm having trouble setting this up. I've defined Sublime both as EDITOR and as VISUAL in the houdini.env file. But I can't get it to work properly from within Houdini.
For example: in the case of wrangles the keyboard shortcut doesn't work, or even if it launches the editor then changes and saving from Sublime will not work. But if I right click the vex editor and select from the menu Expression > Edit in external editor Sublime will work. It gets even more weird if I try to setup a shortcut for python editor.
I'm not sure what to try next.

I will answer my own question here in order to spare anyone else the trouble.

The confusion for me arose expecting a similar toggle like in other places in Houdini.

Yes, they do. You have to enable point snapping.

Cheers

Here is a screen of my snap settings. The points do not snap no matter what I do. I am starting with a polygon curve, if that counts.
Edit: also have Vulkan enabled... I've been hearing there might still be some bugs with it

This looks pretty dope? Can you breakdown a little what and how you're doing?!

Have you tried labs uv-transfer?
Input:
1.any spline like object
2.corresponding spline

create a clean sweep from the spline with uvs and use uv-transfer.

This is quite handy. Thanks!

See if this works for you:

I don't believe so. I am working with cad models, so I don't see how it would help.

Use this hda:

This is nice, but the biggest problem it has it works only on quads. That thing in 3ds max can be used on CAD geometry.
I'll try to see if I can post some screenshots of what I used it for.

Looking for a way to achieve this functionality in Houdini:

Link to 3dsmax docs for illustration... [help.autodesk.com]

Very useful in a lot of situations. Can't find nodes that offer this, but my experience is very limited.
