The "short" question here is - please explain the differences cited below between what is cited in you documentation and what is shown in the "yexample" avatar's animation - The "yexample" animation is in reverse order cited in documentation, and the bones are 1) nowhere near the mesh and 2) conflict with the movements of the mesh in the animation.


The following is the description of FingerR0_ExtFlex from your documentation:

"FingerR0_extFlex: - The right thumb goes to Extended (Frame0) to flexed (frame 30) in a closed position, as when in a fist. In the middle of animation (Frame15) it should be in idle pose."


I have imported FingerR0_extFlex.dae from yexample into Blender -


Looking at the mess of the right hand, and specifically for this post, the thumb - link to screenshots at end:

Not only is the animation in the exact reserve order, i.e. closed position to extended, the thumb is anatomically reversed from frames 19-24. The animation ends with the thumbnail pointing "backwards", bent down, and toward the body of the avatar!

Side note - Definitions used in previous paragraph are per the description cited at the top - note that the "closed" / "fist" position doesn't look "closed" or "fist" to me.

Now, go through the animation screenshots focused on the right hand bones... they start about 6" outside the mesh, and end with the thumb bone ending near the right arm elbow in Frame 24.


Below is a breakdown of what I'm seeing in the mesh of the thumb - not the bone, while it's visible - referencing included yexample screenshots in the file linked below. These screenshots are prefaced by "yexample" before the frame # in the filename:

Frames 0-12 are same frame - thumb in "fist" position (doesn't look like "fist" position to me, but using your definition)

By Frame 16 - thumb pulled back in completely unnatural position

Frame 18 - lower half of thumb pulled back completely and thumbnail still pointing "forward"

Frame 19 - lower half of thumb now pulled back completely, way beyond possible, and THUMBNAIL IS NOW POINTING "BACKWARDS" - TOWARDS the body.

Frame 24 - final frame - lower half of thumb now extended COMPLETELY "BACKWARDS", again way beyond possible, with top half of thumb still bent downward with THUMBNAIL POINTING "BACKWARDS" TOWARDS the body.


For reference, I have also included screenshots of our "FingerR0_extFlex" animation. These screenshots are prefaced by "CapJ" before the frame # in the filename, and were done per the animation description cited at the top - "extended" to "fist" position. Bones are inside the mesh, where we expect them to be...

This line of questioning will extend to the other fingers, as - for example - the R1 finger's mesh ends with the last / end knuckle section being to the rear of the the body around rib cage level - about a foot separation from the middle knuckle section - and the middle knuckle section ending in front of the body lower near the rib cage - about a foot from the hand...


Thanks!
