I took at look at your file cuz I’m still trying to learn about kinefx
I exported the fbx with a rop character output, maybe I did it wrong
looks like meshes are interlaced in the bone heirachy
all the skeletal meshes I’ve used in UE have the bones separated from the geo
with all the geo just skinned to the bones
so something like this would be fine, as long as all the objects under root are bones only
I’ve never tried mixing in meshes in the bone hierarchy while having skinned meshes outside, so I dunno if that works
