Inverse copy scale

Anyone know of a way to copy the scale of one bone, but have it inversed? Just like you can with the copy rotation bone constraint?

I have four bones for a human heart model and I want the atrium to get smaller when the ventricle gets bigger.

Hi,

a transformation constraint with a reversed range should do it.
See : http://www.pasteall.org/pic/69940

Thinking of it this is weird that we don’t have an “inverse” checkbox for that particular constraint…

Thanks!

I took some fiddling but it works like a charm! :slight_smile:

And yeah, I found it weird when I went to the copy size constraint and there was no inverse option.
