import options in 2020.1

The up vector option is a godsent!

Could we also get a "visibility keyframes as activate" option?

Why:
Currently when keyframing vibility, it's imported as renderer.enabled keyframes instead gameObject.active.

The problem with that 3D animation softwares do visibility inheritance (gameobject.activate) so when you keyframe the parent the children hide as well, with import keyframing renderer.enabled instead, that breaks as it won't hide the children.

 

Ideally they would add an option to use gameObject.active or renderer.enabled with copy of the key to the children. Just disabling the renderer is less intrusive as you may want to keep other components enabled.

 

That's a good alternative.
