Hi Adam, Thanks for the heads up and forwarding this on to your colleague, that’s much appreciated. I did check the Inputs and all was as it should be.
@Raffaele, Adam I’ve uploaded a video of the how the relative offset is not working as expected (I should have thought of that in the first place!) - https://dl.dropboxusercontent.com/u/5781634/Shape_Correction_using_node_Editor/Shape_Correction_using_node_Editor.mp4 . it’s a simple rotation from the lower leg – the duplicate leg mesh on screen right deforms and follows as expected. However once I sculpt any changes on the duplicate, return the original leg to its zeroed pose - then the sculpted change is not maintained relative to the joint. I draw a few red squiggles to outline approx where the offset points should be when we return that original leg to its original position. I hope that’s clear. For the this video I didn’t bother assigning a blend shape corrective as its working as required – I did however test this on earlier experimentation and it still wouldn’t work (for obvious reasons). Anyway – I’m sure I’m missing something stupid – although Raffaele explanation sounds like the root cause. P.S. - @Adam – Yes I have run into Derik a few times, he is taking the MA Digital Effects course – I shared some biscuits with him a few months back, nice chap!

I will fwd you any correspondence I get back My first thought might be node order. Select your mesh, and RMB on it. Choose Inputs > All Inputs. In the stack, drag your blend shape node below your skin cluster. (MMB) I can't remember if its mmb drag the skin cluster above the blend shape, or vice versa. One of them should do it though. One heads up... If you use NG skin tools, I noticed a weird bug where an NG skin display layer node inserted somehow into the stack prevents re-ordering. If you can find this node in your node editor, delete it, and you are good to go. I have only had this happen once, but thought I would bring it up anyways. PS. one of my colleagues Derik Gokstorp is down your way doing his Masters at NCAA . I imagine you've run into him a few times.

For example, it appears that this only works correctly if the manipulation of the points is sympathetic to Global transforms. If I try for example to rotate the lower leg backwards, and move some points around the knee and calf to simulate a better pose deformation; when I reset the joints back to zero, the points do not keep their relative offsets correctly. Instead it appears the offsets are global values - not relative. Therefore the points begin to collapse into the mesh. I know there are a few plugins we can use - but thought this may have been a tidier approach. Anyway – if anyone got it to work we would love to know.
