How to put animation keys in autorig H16?

Moin,

your question seems a bit unspecific. You don't want to put keyframes into a rig, obviously, but on controlling “items” (nulls or whatever you want to call them).

If you do not want to extend the autorig-created setup to add your own animation controls (which I would suggest doing), you can grab the pose tool and start posing your character. Whenever you grab a “bone” to “animate” it, you can set keyframes on those channels that you modify - do it once in autokey-mode to tell Houdini that you want these to be autokeyed, then Houdini will capture later tweaks automatically.

Does this answer your question? Else, could you be a bit more specific about how far you got and where you don't know how to proceed further?
