The model was created using Cycles but should work with any renderer that supports PBR materials.

The model was created was created in 3.5.  The model can be opened in earlier versions but the Mix Nodes that multiply the Ambient Occlusion maps to the Colour maps in the materials will need to be manually fixed if using anything prior to 3.4, and the meshes don't appear to link to the armatures properly in version earlier than 3.0
