Hi, I have this plugin which have this useful node but i don’t have source code for this, so it must be possible some how.
Hm… Do you have link to the plugin?
this one is very old problem, that the ik plugin from http://www.ikinema.com/. I don’t use this anymore, not so updated, and cause i can write my own ik node for project now.
Oh, I need the answer of this question, and it seems that you’ve already solved this long time ago.
Wish I could reach to the knowledge.
