I have ElementaryOS (on top of Ubuntu 20.04)
Loaded VRM ok, Webcam also works (debug mode show tracking working) but the model don't move or either blink)
(I use the same VRM in vseeface in Wintendo without issues, i created it with uniVRM from Unity)
(by the way, awesome work)
PS: also test with original vrm, but the model didn't move
