Now I have two objects, "A" and "B", and "A" is copy from "B" use "A = pm.duplicate(B)[0]", then I did connect attribute like:
pm.connectAttr(someBSNode.outputGeometry[0], A.getShape().inMesh)
and "A" somehow moved a little bit in my view ( I don't know why), then "A" and "B" no longer overlay precisely, but I checked the transform information about these two objects, they still remain the same, like images below: enter image description here enter image description here
I want to know how to calculate the world space coordinates of objects in maya? What attributes affect its location? Which is the M matrix in the MVP matrix?
