Grimrock

I made a monster that uses a Goromorg Shield.
When the monster walks, or steps forward a bit for an attack,
the shield does not follow along, until the game object is in a new tile.

Goromorg Shield does not seem to respond to "parentNode".

What is it following, on Lindworm and on the wizard?
Do I just need to add or rename a node?
I tried logical center of gravity ones like spine_1, spine_2, and stomach,
which both Lindworm and the wizard have.

local_srt

Really? Hmm.
Lindworm did not show local_srt animating (or it did not load the animation into Blender with "walk" for me to see it).

I'll try animating it now, after-the-fact, and having the mesh and the armature copy transforms of the root node to try to re-bake animations "as is".
And maybe I'll rethink how I make armatures and animations, if I want more caster monsters.

Does not animating local_srt cause any other issues?

I found it less of a hassle to just rework shields, than to redo animations with local_srt moving.
And that allows for altering how shields work, e.g., they don't need to work on every hit.
