Currently working with J'n'S and it's fine so far. The only thing I'm missing is to set up my artwork for up-left, up-right, down-left and down-right.
J'n'S (and Bq_HeadRig as far as I can see from the videos) only interpolates between up and left (for instance) to get up-left. This is not working an all cases, especially when you are working with shape layes and outlines and a bit more complex characters than circles and squares.
and it also does the good job with eye blinks,mouths where the Headrigs dont do stuff like this.all i think is, its just the same work with face-turn as using Headrig and Headrig its only do with face proportions..i know..i just wonder which one should i use for rigging animation..should i use both? for rigging face,eye only with Headrig and face,eye,mouth with joystick.....?
I would go with J'n'S since you got more options and possibilities (sliders, switch templates) and it's only 10 Scraps more than Headrig.
If you only want to rig face and eye, J'n'S can do it, if you want to rig more, J'n'S can do it, too. Actual, you can have a rig for every single layer (only left eye, only right ear, only upper lip and so on), getting complex rigs with Headrig, too. But, J'n'S seems to be more comfortable, when it comes to greater complexity.
