This mode is equivalent to usImplement one more way of inheriting None plus a Copy Scale withscale from the parent
Offset from parent on the childbone, as an addition to the choices introduced in D5588.
This new mode inherits parent scale as if the parent and child
were not rotated relative to each other, always applying parent
X scale to child X scale and so forth. It is quite natural for connected
bone chains with coherent roll, like limbs or tentacles, and is well suited for chainfalling
roughly between Average and Fix Shear in how closely the
parent scaling is followed.
Currently this can be achieved by using Inherit Scale: None plus
like tentacles.a Copy Scale with Offset from parent on the child; however, Implementing it as a built-in has the advantagethis
that it would be properly tracked in the Local vs Pose spaceis cumbersome, and loses the distinction between true local and
conversions, as well as convenienceinherited scale in the child's Local space.
This is also how the Copy Transforms constraint mix modes work.new mode also matches how the Before/After Original mix
modes work in the Copy Transforms constraint.
On the technical side this mode requires adding a right side
scale matrix multiplication into the Local<->Pose conversion,
in addition to the existing two left side matrices used for
location and orientation.
