A good way to light up characters in open-world?

Hello everyone,

I’m building an open-world game, and would love any idea on how the industry doing for character lighting in the open-world or MMOs? I tried to search for posts and GDC lectures but hardly find content related. I’m planning to light up characters separately with blending to the environment lighting, but haven’t got an idea on how to blend them properly. Appreciate any info or related links, thanks very much!!
