[X3D-Ecosystem] Please review this Blender Python before I try to incorporate into an addon

[John Carlson]

What I have discovered in my journeys is to that locations seem to added
together, such that if humanoid_root not at 0,0,0, then it gets added to
sacroiliac, etc.  that is, if you go down the leg or arm, they will go
upwards in Y, despite perfect location values appearing in Blender.  It
probably doesn’t help to do any kind of coordinate swapping or matrix_local
vs matrix_world.  What I will look into is doing delta transforms next,
subtracting child center from parent center and assigning to delta
location.  Another way to solve this is provide a flat transform hierarchy.

I will check in an example which shows this—eventually.

Anyway, I’m discovering new ways to curse at AI, finally taking over from
them, despite luring them with $20/month. Probably you.com is better for
the end user and worse for the AI provider.  It just seems like you.com
could be blocked by the AI providers.

Blender’s not much better than AI.
