Ni-Mate by Delicode is a great app:
"NI mate is a unique, cross-platform, cross-sensor real-time motion capture suite that's been designed for anyone to use. No markers, complex and expensive camera setups, long render times - just install NI mate, attach a sensor and open up your favorite 3D suite."
Prior to a Windows10 update, they supported the sr300 and the facial animation possibilities, live in Blender, were excellent.
Here is the current situation:
"We believe the "CreateInstance()" issue is that the runtime on your computer was updated, and the RealSense SDK is, for some reason, not backwards compatible. Another problem with the runtimes / DCM is that they occasionally update the sensor firmware and break compatibility with older software. If you could find an older version of the runtime / DCM you might get the current version of NI mate working with your sensor. I spent a while searching through the Intel webpage, but it seems like they don't have links for the older versions...
"starting with NI mate 2.13 unfortunately the current plan is to move away from the official Intel RealSense SDK and utilize the alternative librealsense driver without the face recognition algorithms. Due to the massive amounts of complications with sensor devices and runtimes we couldn't justify continuing the support for the official SDK with RealSense."
The above is in response to this situation of mine (prior to the mentioned update I had excellent results, now no function whatsoever):
"after reloading Windows10 this fall, and i think the error i get might be relatively simple?
This is version 2.12
Thanks again for your help--
(: Input 1 quit normally.

Any ideas? help? suggestions? Thanks.
