How to make characters?

Hi so I’m new to Unreal engine and I’m not sure if this is the appropriate topic but whatever.

So, I want to create my character and I have a few questions
1.Do I make it all in one editable poly / editable mesh or different meshes for each moveable part eg: arms , fingers

  1. Do the bones systems have any rules to follow like bone names etc, Note that this is NOT a humanoid
  2. for the animations , Do I make it in 3ds max or in unreal Engine ???

Thanks for any help, I use 3ds max for my modelling

Closed, because of duplication:
