Thanks for the insights @PirateJC & @JCPalmer but when I have multiple animated meshes that I want to be a part of the one animation on export, I uncheck the (counterintuitive) GLTF export option “Group by NLA Track”. This aggregates the separate animations and in Babylon.js they simply show up as an AnimationGroup called “Animation”, a name I can’t seem to edit anywhere in Blender that I’m aware of.
Outline with multiple animated meshes:
GLTF export settings with “Group by NLA Track” unchecked:
How it shows up in Babylon.js - just named generic “Animation”:
And in the inspector (2 GLB imports, each with aggregated animation group names of generic “Animation”)
Likely there’s something I’m not understanding when it comes to Blender animation.
If it’s not possible to change this aggregated animation name in Blender I guess I could just change it somehow in code, after the GLB is loaded into Babylon.js.
