Maximo upload issues "Sorry, unable to map existing skeleton"

[defaultqt1zutvepfhe]

Hi,

I made this model using blender but when I upload it on Maximo it gives me error. As I'm new to blender, I might have made some mistakes while making this model. Can someone help me correcting it?

Thank you.

the model is not a standard Fbx so Mixamo will not read it... yes that part is easy to fix but you have 3 different humans meshed together [out of sync] and I don't know which one you want uploaded
