Is there a Simplify Curves addon for Blender 2.80? I'm using the latest Blender 2.80, and I notice a Simplify Curves addon at preferences> addons> search:simplify I see Add Curves:Simplify Curves, but then it says upgrade to 2.8x required.
What is currently the way to simplify a complex animation F-curve?
Sometimes I like to record a complex object movement, but I used to love to then Simplify the curves to various degrees with Simplify Curves addon.
Thanks for any ideas.
Select your keyframes on graph editor.
Press "o" Select SMOOTH KEYS. That should "simplify" a little bit better your curves.
I remember the function "simplify curve" is available for grease pencil, but I don´t remember seeing it elsewhere. Please paste a screen capture.

I hope this works for you. If it does, please vote me up and mark me on the checkbox to the left side of this answer. 
Thank you.
