Alex is rigged with Autorig pro.

What's in the zip file:

You'll have 2 addons included, proxy_picker.py and rig_tools.zip

One blend with materials ready for eevee (and working for Cycle as well).

Installation:

To enjoy all funcionalities, install the addons proxy_picker.py and rig_tools.zip, unless you already owned the autorig pro addon. Installing autorig pro and rig_tools.zip at the same time will cause problems.

Be sure you have check the Auto Run Python Scripts in User Preferences/Files.

You can now append Alex in your scene.

Remark:

You can enable the mask for the body corresponding to the clothes. However, be aware that this will increase the ftp rate.
