Terrible things can happen when something is wrong with the delta table. Poser can crash, but there are worst thing that can happen.

You have a figure with one faulty morph, when the morph dial has a value 0 nothing happens and appear to be normal. You change the dial to 1 and strange things can happen, Poser crash or nothing happens, the figure is morphed and all is ok. You apply other morphs, pose your figure, move it and in some moment the figure has no more head or the eyes get out of orbit or who knows what else can happen. Or you save the scene that looked ok and when you load the pz3 again tragedy!

How do you find what/who is responsible for all the malfunctions?

As for the blend parameter I have no idea, the same for the joint dials !

Stupidity also evolves!
