Blender - XNA Rotation Animation Hack and MonoGame

hi, has anyone done blender fbx export and ever worked with this feature before ? “XNA Rotation Animation Hack”

is this still needed in latest monogame versions ? will an export with latest blender of a model with bones in fbx work in monogame ? latest blender version is 2.78c. has anyone built models with bones in blender 2.78c with animations and custom skinned model processor and had success with animations at runtime ?

We have no idea what that hack is (I’ve never seen that option before), so it’s difficult to answer.
