I have modelled a custom mannequin and created a skeleton for it in Blender. The skeleton copies the Unreal’s mannequin’s skeleton perfectly (hierarchy and bone names all the same).
When I import this model and select the Unreal’s standard skeleton to use with it, it does not complain. But when I run an animation on this model, it gets twisted so much that it gets basically unrecognizable. I thought I has something to deal with the initial transform of the joints when imported and tried exporting from Blender with various different settings but that did not help.
Here is the linkto the stack question with illustrations, it also contains .fbx file with my model/sekeleton.
really hope you can help me out with that.
