I also have to permanently log me in each time I start the Launcher or Houdini itself.
This behavior is new to me and started a few weeks ago. Before that I only had to manually login every 2 weeks or so, so I suspected an error on my side, but obviously this is intended or a bug of the later versions of Houdini 21.

Happy New Year

Blender's Motion Tracker is indeed very powerful, I've been using it successfully for many years.
In the end I got the best and most reliable results with a few (8 to 30ish) manually placed and supervised tracks per frame, not using any of the "automatic" options with hundreds of tracks where you end up searching for not-so-good trackers and cleaning them up takes longer than doing a proper manual track in the first place.
The only thing that Blender can't handle is animated focal lengths (zooms). The solver can't deal with them.

A few years ago I invested some € in SynthEyes though because I had to track dozens of anamorphic shots with extremely weird lens distortion and animated zoom which Blender couldn't handle. I didn't regret doing so and it works beautifully in combination with Houdini (and Blender and Fusion).

Just started watching this brand new MPM fundamentals video https://www.youtube.com/watch?v=fDmJo3zpb1g [www.youtube.com]

And right at the start it says "...capable of simulating small scale fluids...".

Now I'm excited and will watch this.
