Use custom actors / new scene?

[HanaZora]

I have created a couple custom characters in the racemenu mod and was wondering if there is any way for me to set up animations for them? I tried cloning myself and then loading a new preset that i saved but the bodyslide values don't carry over so it ends up being the default female skin. Plus, sometimes the hair and face glitch out and look extremely weird on my clone when i switch character presets.

 

Also, I have seen a bunch of screenshots of people using their characters in classrooms, bedrooms, modern interiors etc. how is this done and how can I do it? What mods are there for custom environments for my scenes?
