hi, (not English native). If I select that option, the unnecessary bones are ignored by the program and improve optimization in my game? or is just a form of optimizing the viewport in the hierarchy.
Thanks.
This is taken from the Unity docs on "Optimize Game Object":
When turned on, the game object transform hierarchy of the imported character will be removed and stored in the Avatar and Animator component. The SkinnedMeshRenderers of the character will then directly use the Mecanim internal skeleton. This option improves the performance of the animated characters. You should turn it on for the final product. In optimized mode skinned mesh matrix extraction is also multithreaded.
So yes it not only cleans up the hierarchy view, but also improves performance of that game object.
