Dyltom's BeHuman Character Pack Red is a collection of human-like characters for Mount & Blade II: Bannerlord. They are made with care and I have tried to make them as human-like as possible. They are very easy to install and use. You can create and edit them yourself. There are a lot of skins to choose from and you can customize your characters as you like.

How to install them on NPCs:
There is a skin installation pack called Detailed Character Creation. You can install the skin on to any NPC. To install the skin, open the file with a text editor and you will see a line that says 'Key=xxxxx'. You just need to copy the value and save the file.

To change the appearance of an NPC, press CTRL + F (search function) and search for the NPC's name. You will find the name and the face code. You just need to replace the face code with the face you wish to use. To save the file, press CTRL + S.
