Mesh must have Armature modifier assigned.

And how to do it?

select mesh object
switch to Modifiers Properties (has wrench logo)
Add Modifier -- Armature. Target to Armature object. Do not apply.

Should be able to export mesh with skeleton.

Mesh must have Armature modifier assigned.

Do not import qcs. Import meshes and animations separately.

Hands are imported as separate mesh+armature, then bone constrained to knive v_ model

Duplicate mesh. Apply shape key. Export.

Import smd instead

>the name of objects contain unicode characters and may not compile correctly

Export it

Make weapon_bone as child of r_hand for now

Getting same error on Steam version.
To reproduce, import only animation file as new object. Appending the animations onto mesh makes it still un-animated.
