Import Hierarchy doesn't add RootNode to hierarchy

Project: https://playcanvas.com/project/849912/overview/animation_test

When importing this model as a model asset, the hierarchy has an Entity named 'RootNode' added:

However, as Import Hierarchy with render assets, this node is missing/not added

The animation file has paths that uses the RootNode which leads to incorrect animation being played.

Example animation path

RootNode/Ausschalecke/Ausschalecke_Root/Ausschalecke_Ecke_4_Root/Ausschalecke_Ecke_4/Ausschalecke_Ecke_4_4/

Good day, when I try import runtime glb like as binary, my glb not have "RootNode" in skeleton, when I export, and I cant use old animations with binary-glb, it's affect new characters for miniroyale.

@DarkKelt for the short term, can you use https://developer.playcanvas.com/api/pc.ContainerResource.html#instantiateModelEntity instead? Or does that have the same problem?

Alternatively, create an empty Entity, reparent the Entity created by the contain to it and rename it to be RootNode as a temp workaround

@DarkKelt Just to also check, are the GLB binaries that you load at runtime, are they models only or animations as well? If you can share a project or the files, that would really help too

instantiateRenderEntity work good runtime. I check containers, after some actions i get correctly created model. When your importer FBX create glb model from source how i understood you change bone hierarchy and connections with vertexes. I check imported fbx and other glb from other source with hierarchy.

When I import raw binary glb, it's not have "RootNode" and animation not worked corectly. That's why I asked Max about convertation pipeline.
