The basemesh was made with the most recent version (as of July 2024) Blender 4.1. It will work with Blender 4.0, but the Rigify menus may be missing, but the rig will still be fully functional. Opening the basemesh with any older versions won't work correctly, the rigs will be invisible and therefore unusable.

As this is a basemesh, it is designed to be built upon. You cannot redistribute this as is, but if you use it as a basemesh and retexture it, give it hair and clothing etc, then you may use it for any project, you just can't download this and throw it straight into your game.

As of v1.0 I only have 6 presets. Now that the Basemesh is released I can take my time and build upon it by adding many more faces for different characters which will allow you to get more varied characters a lot more quickly.
