Why did it work in Poser Pro 11 then?

this is also not the only issue I found.

I have some bumpmaps set up to change (skin folds / wrinkles) through an animated "blender" node (new node -> math -> blender) and added dependencies to certain bodyparts. i.e. if the character smiles or raises their eyebrows, the bumpmap stregth goes up and the wrinkles become more visible. These behave wonky as well now. Even though they should be at minimal strength, they're on full strength.

I mean, are you saying that I have to rework all the mats for my 30 or so character models to make them work in Poser 12 ? Oo
