The 'Hand' output from the vuo node is in reality the wrist position from NImate which should work adequately for your requirements.
NImate can output hands with fingers if used on a Windows machine with Kinect v2.
When NImate sends hand and finger coordinates it overwhelms Vuo. (I only tested this with Kinect 360 (v1)).
There is also a bug in NImate with switching off hand tracking.
NI mate sends the hands even when the tick box setting for them is off. You can force disabling them in the skeleton tracking settings as follows:
Enable the hands tick box,
Clear all the OSC fields for the finger joints,
Hands/Fingers will no longer be sent.
This whole crowd funding thing on the face of it sounds good but it seems like it could just get a bit complicated. If there were more Vuo users overall crowdfunding would be unnecessary. Do you pay to advertise Vuo anywhere? Maybe we could crowdfund a marketing campaign and see if it helps?
I get the feeling a lot of the founders are no longer here because it's just taking too long to mature into a fully featured product, a whole new batch of Pro users would be a boon. Having watched the release of Resolume Wire over the last few weeks the interest in node based tools is out there if the marketing is good.
Will the Metal implementation include Shadows from Lights that has been one of the most voted for features for a looooooooong time. I'm getting a little impatient for it.
As for FX plug support, I see two or three users who want it, and FinalCut users are very thin on the ground these days. I don't even remember seeing a job advert requesting a FC editor in the last few years. If you were to implement a cross platform output: making Adobe plugs would make much more commercial sense IMHO.
I assume you'll update to the newest NDI at some point soon too.
Thanks for all your work to date.
