What will you be using for your main 3D package for final compositing all the components together?
Being new to character modeling, you will have to do a lot of your own research, watch tutorials on YouTube and a lot of trial and error, as there is no one answer to your questions.
I would imagine Artist-C to be responsible for the cloth weighting to the character, or the use of mesh colliders, fairly tedious process to get right, many times you can just hide, or mask parts of the character mesh to alleviate break through.
I have never tried using a MH model to import as a target character inside iPi for retargeting, maybe someone else here has, I believe only Blender has the plugin for importing MH models, but then you may be able to export it as an FBX of the character made, it has to have a skeleton of course, see if it will retarget properly inside iPi Studio, if so, then re-export it back out of iPi as an FBX, then in your 3D package you may be able to import it with all animations you set to export, try it and post the results if you would for others.
May want to download Autodesk FBX Reviewer, much faster to check your exported FBX file in it to make needed adjustments inside iPi again if needed.
Here is a link for a fairly new facial capture software: Free trial download @
