Armature/Skeleton structure

Hi i noticed that if a model has a not connected bones in it , it will not be properly loaded .
While if you " Fill Between Joint " , it loads and works as well .
( i work with blender ) Is there any fix for that , using separate bones is just more comfortable .
And i need to load it as blend , for a better structure of work .
this is the error i get , (seen it in other treads )

" animation.BoneTrack can not be casted in animation.SpatialTrack "

Hi,

Please provide the full error stack trace.

What do you mean by “Fill Between Joint”? You mean connected joints?

What JME version are you using?

You better export the model to Gltf and load the gltf file in JME.
