Absolutely agree. For everything Blender does awesomly good there's some thing missing you'd never expect to be missing in the first place. Updaing a motion path manually is one of these things.

Is there a reason this isn't a feature, yet? Because I can't see this being to useful if the motion path doesn't reflect the changes made.

Even better yet - have the motion path be editable directly inside the 3D view. Maya can do this for example. knowledge.autodesk.com/support/maya/learn-explore/caas/CloudHelp/cloudhelp/2018/ENU/Maya-Animation/files/GUID-FC9AE83B-11C9-45C2-A364-AFCDF23BD125-htm.html

I absolutely agree! I haven't animated much but this was pretty standard in Source Filmmaker if I recall correctly.

I think a better implementation would be a checkbox for motion paths. When enabled, changing the keyframes would directly affect the motion paths in real time.

If this feature were in, you could also go about adding keyframes to the animation based on the motion path. For example by draggin one of the dots to a new position and pressing 'i' and so forth though this is a different suggestion.

* @MizManFryingP * - Yeah, it's really boring have to click 'update' every edit. Even if you add a shortcut key, you must be in the same window.

* @Vinícius Fidelis * It's not 'boring' it can even be misleading if you aren't careful enough. If at some point you fail to click 'update motionpath' and still rely on the frame ticks displayed along the path to reflect your animation it's easy to make mistakes. A motion path needs to be a direct and reliable reflection of your frame spacing. That's what it's for.

there was an addon on 2.7x called motion trails which did that and allowed to edit the curves which modified the bones' movement. It was insane. Just someone who could adapt this addon for 2.8 would be a real life saver.

Does this still work with V3? I am running 3.4.1 as of this writing.

And why has Blender not implemented something like this natively?

So... 3 years and it's still not implemented.
