View source for Stream Scene Share

To make it easier to follow along or get caught up, checkpoints of my scene file are be periodically saved and uploaded to a publicly accessible web directory<ref>''[https://hip.johnkunz.com/ttv https://hip.johnkunz.com/ttv]'',</ref>.

Whenever a new scene file is shared, a link is posted in Twitch chat. You can use this link to download the file and open it in Houdini.

If you'd like to simplify this process, you can use a shelf tool<ref>''[https://www.sidefx.com/docs/houdini/shelf/customize.html sidefx.com/docs/houdini/shelf/customize.html]'', </ref> which calls a script when clicked on. In this case, fetch the most recently shared scene and merge it into your Houdini session.

You can [[:File:twitch.tv.johnkunz.shelf|download the .shelf here]].  Install it by placing it in this location $HOME/houdiniX.x/toolbar/twitch.tv.johnkunz.shelf



== Create the Shelf Tools Yourself ==
If you prefer a more hands on approach, the shelf can be added manually by right-clicking in any empty shelf area and clicking "New Tool...". This will raise a dialog window where the tool's name, label and icon can be defined<ref>''[https://www.sidefx.com/docs/houdini/ref/windows/edittool.html https://www.sidefx.com/docs/houdini/ref/windows/edittool.html]'', </ref>.

The Python code used in these shelf tools can be found below, Python2 and Python3 are both supported.
