As simple as the title makes it seems, really. The problem arises when animating, where you can move a bone to the correct position, keyframe it, and then you notice you have several keyframes where the bone position is the same, simply because the value kept increasing - even tho the position didn't change.

Including a file with an example.

If this is intentional, then i would love to hear why - and how i could avoid it.

I was going to say that turning ON Affect Transform should take care of that, but apparently it does not work correctly

As a second workaround, I was going to suggest to use visual keyframing

That seems to create the keyframes that you want, can you confirm?
(note that you have to change frames after disabling the constraint to see the keyframes are in the correct location)

Regarding Affect Transform: this seems to work as expected for a Limit Location constraint, however seems kinda broken for the Limit Distance constraint

@mano-wii : interested?

Hi Phillip. I should've mentioned that i've tried pretty much all the options on the constraint itself. Much like you, i thought the Affect Transform toggle should do exactly what i wanted, but it didnt, and i guess i have no idea what it actually should do.

On the other hand, the visual keyframing has worked just fine. Thank you! 😄

Still, i wonder. Are we looking at a bug or at a set of thought-provoking decisions?

The Affect Transform issue is a bug, will update the report description

Philipp Oeser changed title from ~~Limit Distance Constraint limits visually but not in value~~ to Limit Distance Constraint, Affect Transform does not limit the transform system correctly
