What you will want to do is prepare before hand the various figures you want to have combined. For example, say I want to have a pregnant Victoria 3, a buxom victoria 3, and a male morph enhanced Victoria 3 all together. I first go through one by one and create these figures and save out new cr2's for each one. Then I can start a new scene, using the Null as usual, and load in each of my characters. Then everything should work fine. But to have multiple figures in the scene and try to be customizing them all within the same scene will cause problems. Just remember that all these improvements to Victoria 3 (and the accompanying learning curve ;) ) are worth it. Our intention is to make things as easy and as versatile as possible, and though some of the current procedures with these new innovations are sticky for many right now, in the future, this should all become much easier.
