all of the character addons work fine with V4.2 the only difference is that due to direct requests from quite a few users who complained that having the morphs automatically inject on load made her more memory intensive than she had to be for their purposes, DAZ has set up V4.2 to be completely injectable. so characters that do not use injection poses will not find the morphs they use unless you inject the figure with the morphs++ morphs first. hopefully merchants will see the benifit of including Injection morph poses in the future, just as they did with V3.
