Delete these threeSo, I have installed some Character models. Different to the base G8 model, thoose have a pussy. But I suppose it has not all the features the pussy from the "Golden Palace" asset has. Now I cannot just apply the Golden Palace pussy, because it would overlap the default one and a double pussy looks awkward. I just cannot find out how to remove the default one.

As for your other question, technically no. There are G3 to G8 morph converters but I don't know anything about them. The textures are the same though.
