It’s really designed for animation, but I wrote a tutorial using it for saving poses too. You can find it here:
It’s REALLY handy for saving poses, even if you do static scenes. I use it all the time.
Pose your figure (or a light, or a camera or…) and add a Puppeteer dot; try another pose, add another dot; try a third, slightly different one from the second and add a dot; decide that you preferred the first one; click the first dot and the figure will revert to the original pose.
An awesome, safe way for trying out different things to see which works without having to save different scene files, pose presets or anything. Of course it won’t affect the surfaces, though. And undo doesn’t work when you change the pose using puppeteer, but you can use it to your advantage too.
