Makehuman Scripting

Generate 520 characters in MakeHuman using the scripting plugin

The following script is written in Python and uses functions built-in Makehuman software.

It generates 520 female bodies (130 for each femininity step from 0 to 0.3) with random muscles weight hip circum and WHR. It writes on a .txt file the parameters assigned to each character.

To use it you have to load in the plugin for scripting within makehuman and have downloaded the mhapi for developers from here ( https://github.com/makehumancommunity/community-plugins-mhapi )
