>>55603965Rigging is a collection of sliders attached to moving parts on the model. The slider goes from one state to another state, ie left from right, up from down, open from closed. A model's full rigging is just a really dense web of these sliders controlling a lot of different points. Capture software translates movements in the camera's preset focal points into adjustments to corresponding sliders on the rig.
Sometimes inaccuracies can arise from slider tolerances, ie it's too easy or too hard to transition from one side of the slider to the other and doesn't match the actual data the capture software is providing, or because the capture software inherently must translate 3d image data into a 2d plane and euclid fucking hates that.
So to answer your question, the possibilities are:
Biboo's rig needs adjustments to its mouth slider's tolerances, because her resting closed-mouth face is not causing the mouth slider to go far enough to close all the way unless there's an additional mitigating factor, like a facial angle change from posture
Biboo's rig is fine, but the angle and position of her face relative to her camera is causing her capture software to believe her mouth is slightly open when it's actually closed, until she shifts position, like sitting up straighter or hunching over slightly because she's more focused.
Her mouth just normally hangs open and the model is accurate, and it's closing when she's focused on the game.
