This is the "Vertical" option in 4.0.0. As you can see from the widest point of the model, the ooze shield is modelled vertically upwards, the lower portion is modelled respecting the "Sidewall Angle Change" parameter
However in 4.1.0, the ooze shield is modelled totally vertical all the way from the widest part and not respecting the "Sidewall Angle Change" parameter
