Hi everyone, I've been experimenting with motion capture and I'm having some trouble getting consistent foot tracking, especially during faster movements. Sometimes the feet seem to slide slightly even when the rest of the animation looks fine. For those who have worked with iPi for a while, what usually makes the biggest difference here: camera placement, calibration, lighting, or something in the tracking settings? I'm still learning the workflow, so any practical tips would be appreciated. Thanks!

Two Kinect v2 — device factory returned null — libusbK installed, OpenCL confirmed working Hi, I'm running iPi Recorder 4.7.0.98 on Windows 10 (10.0.19045.0, 64-bit) with two Xbox One Kinect v2 sensors (Model 1520) and cannot get either camera to stream. Both cameras show as Ready on the Home screen, but display "Could not open a device" when I go to the Setup tab.

Hello, please make sure that you're using the latest version of iPi Mocap Studio and please install version 0.8.7 of NVIDIA AR SDK from the following link: https://www.nvidia.com/en-eu/geforce/broadcasting/broadcast-sdk/resources/ The thing is that support for GeForce RTX 50 Series Graphics Cards was introduced only in NVIDIA AR SDK 0.8.7 (version 0.8.2 does not support RTX 50 Series). For additional information please read the following release notes: https://docs.ipisoft.com/iPi_Mocap_Studio_Release_Notes#ver._4.6.7.269

Hi, I have problem with Ipi soft studio Everything used to work perfectly. After swapping my graphics card for a newer one (GeForce 5070), the AI-based tracking stopped working. Well… it half-works – if I keep spamming “OK” on the popup message, the animation still processes frame by frame, but obviously I’m not going to sit there clicking OK endlessly. Is this some kind of bug? How do I fix it? Everything works fine without any AI tracking, but the moment I try to use any AI feature anywhere, these issues start appearing. See attached image for error
