Blender 0 weight bones Example of the problem: I have 5 objects and 1 armature. Every mesh is skinned to 1 bone and got 1 vertex group, but when I open this ".FBX" in unity and hit 'show all bones', it tells me that every mesh is skinned to every bone what could be the reason for this? I know the problem is in Blender. Opened the ".FBX" in Maya as well and its the same. Tried all kind of exports and cleans and still nothing.
There is an option to export only deform bones in the FBX exporter. 



For this to work you must uncheck the Deform option in the bone properties.
