How to for adding a MH to an LLM for real-time interaction

I am brand new to Unreal and the MetaHuman system. Firstly, my project is an app to teach kids using an avatar that will talk and answer in real-time through an LLM and a RAG (RAG is how it learns the specific topic and learns the student’s needs and personality). How do I use a MetaHuman for a project like this. If I build the MH using the Creator, what options do I select to ensure it will be usable in the LLM. The LLM can use Blender after a mesh map and animations system is used but the pipeline is faulty and horrible to use. I don’t like Blender at all. A friend suggested the MH and I just downloaded the 5.6 and other installs for it. Now, I have to determine if this is useable or not before I spend another two months only to learn it was a waste of time. Setup steps would be most welcome. Help me so I can help the kids. Or if you know where I can get the basic MH of a man and a woman, in business casual, that would really be a godsend. That’s all I need Thanks,
Mike
