@woland Yep thats the one ! thank you so much ! 

Hello , I am having issues with a mapping set-up (for a show that launches tomorrow) in that when we switch down the kit (Mac mini playing the Isadora patch and the projectors), the stages seem to rearrange themselves. Has anyone come across this before / could offer troubleshooting advice ? 

Huge thanks

The name on the file in the screenshot you are providing is "openni-tracker-tutorial.izz". The link I provided is to the OpenNI Tracker Tutorial file, not the Guru session. Please download the file I linked and tell me whether or not it is the file you were looking for: https://troikatronix.com/add-ons/tutorial-openni-tracker/

@woland thanks so much for the reply - so I have the Open Ni tracker and the camera set up is working fine but what I don't have is the patch which is used at the start of the tutorial, which is for a skeleton visualiser 

I have the second patch used in the tutorial but not the first, which seems to be missing from the download file 

many thanks in advance for any help you might be able to offer!

As I wrote on the other post, the OpenNI Tutorial can be found here: https://troikatronix.com/add-ons/tutorial-openni-tracker/

It makes this puppet with the "Puppet Two Segments" User Actors shown in your screenshot. Double-click them to go inside and I believe you'll be able to find the 3D actor inside it responsible for rendering each segment's location using a specific 3d model, and you can then change the 3D Model being used by that User Actor by changing it in that User Actor and then closing the user actor and choosing "Save and Update All".

More about how to use User Actors (in general) can be found here: https://support.troikatronix.com/support/solutions/articles/13000091626-isadora-101-tutorial-11-creating-user-actors

Here's another 3d line puppet by the ever-fabulous @bonemap : https://troikatronix.com/add-ons/line-puppet/

I am essentially trying to understand :

- how I get this sort of 3D visual from the visualiser 

- how to alter the aesthetic of this 

The Skeleton Visualizer actor can be used for a very basic form of this like so:

The aesthetic is changed by adding video effects like Motion Blur or Shimmer in the video actor chain (after the Skeleton Visualizer, but before the Projector actor): 

Alternatively, you could send all this to a Virtual Stage and use the Get Stage Image actor to pull it back in, then apply effects to it, then send it to a regular Stage via another Projector actor. (This would be useful if you wanted to get multiple skeleton sources all together in one place before you apply the effects):

@juriaan
if it's possible to pin one participant's stream to a second monitor, then it looks like I will be fine using Screen Capture. Another option might involve 2 laptops and a capture card...

@dbini

Well that option that Woland pointed out is maybe a solution then?

@woland @Juriaan 
ZoomISO does indeed look like a perfect solution, but I'm on Mac Intel, so that's a non-starter.

@skulpture I use VDO.ninja all the time, but for this conference, it's an annual event that's always on Zoom. 

It could be scaling but it could also be projector antialiassing. Curves don't really exist in a digital world - only blocks of pixels. And if there are not enough pixels you get "steps".
