@h-elwood-gilliland the simplest summary of the initial posting, is that in addition to the existing afterBend flag, there is a need for an afterMorphs flag, which can be applied to deformer channels, in addition to the afterBend flag applying to deformers to force Poser to preserve calculation order when reloading a saved scene. The second part of the request is that these flags be accessible to Python, in order that scripts can re-order parameters as can currently only be done manually (and extremely tediously when scrolling hundreds of parameters) in the GUI. This is my suggestion for a way to preserve operational symmetry of saving and loading scenes. The save currently appears to preserve the calculation order present in the open scene, but loading the scene into Poser collects all of the deformer evaluations before the pre-transform morphs, which changes the effect and breaks working scenes on loading.
