Maybe I am confused about what you want. If you want to have you own figure work with mimic then you need to make it mimic compatible. There are actually tutorials over at DAZ that can help with that info. That can be more involved because you may get odd results. If you are using mimic compatible figures you should only need to select that character and setup you mimic info to animate then export a poser format file you can then import as a pose and apply to a natively loaded character. You can actually see the animation better in D|S w/ out rendering, but the animation tools aren't as good as carrara. Carrara in preview for scrubbing is like molasses in jan running uphill :D Now in regards to what to edit out of the file...that I couldn't really tell you because I have only worked some w/ animation tools in carrara, that slow scrub issue is really a big problem, tries your patience. I think it is the same issue as OGL preview, just made worse by the load.

No need to think outside the box....
