This is why we wanted to reduce this to a single set of head textures (Diffuse + Normal + ORM). If you take a look at the exported FBX you will quickly see that the head alone has a large number of materials already. To that end, we built a python script that uses the Pillow (PIL) library to repack the textures into the new layout which we defined in JSON. Manuel Wagner: By itself, CC3 already provides a lot of information about the exported FBX if you check the “export JSON for auto material setup”, but because every clothing asset and head and skin part has its own texture and UV layout assigned, we needed to repack the textures and UV layout to make the material use fewer textures. In hindsight, this was the wrong choice because the heads that were created with Headshot look way more believable and diverse than the manually configured ones. Manuel Wagner: In the beginning, we did not use the headshot plugin and configured the heads by hand.
