Method
This node applies the tracked skeleton from the NVIDIA AR Body Tracker to the skeleton of a connected rigged character.
!This node requires the installation of the NVIDIA AR SDK, which can be downloaded here : NVIDIA AR SDK. Make sure you get the correct driver for your GPU, Turing (20XX) and Ampere (30XX) use different drivers and they are not cross compatible.
*When running on a media server, the Demolition-NGXCUDA.dll file will need copying to the relevant media server folder. For example, with Disguise, copy it to “C:\Program Files\d3 Production Suite\build\msvc”.

*For best results, use a character with a rig generated from Mixamo. Other skeletons can be used, but results may vary.
