How to use Tracker?

Dear forum,

I’m just too curious all about nodes with names “Track” like:

  • Blob Tracker
  • Track Features
  • Track points

But there’s no single example how to use them AFAIK.
Is it theoretically possible to perform real-time tracking with them to do stuff like
“tracking your finger from camera input and emit particle only from there”?
Or do they only work in combination with ncam?

If I should miss something, I would highly appreciate for any hints.


Hey Yoshiaki,

Those nodes are still in development, and so we wouldn’t recommend using them for anything yet.



Hi Ryan,

thank you for great insights.

Is there any kind of information available which nodes are under development and which not?
Otherwise it would be nice if these kind of nodes get grayed out or clarified in any way.
