+A general overview of some of the tools and workflows used and applied by the Unity Team for the creation of their state of the art Digital Human, Gawain.

-==== RealTime PreViz ====
+They used two different rig hierarchies. One for the body the other for the head.
+==Body Rig==
+Classical full body game rig. Skin weights up to the torso.
+Corrective blendshapes for the hands and the back.
+==Head Rig==
+Combination of Joint hierarchy and over 200 Blendshapes.
+=== Model ===
+Non-deforming body parts like the gum don't have an optimized topology.
+All the hair consists of cards. Hair is exported as a separated object and is not part of the head mesh. It's attachment to the deforming mesh happens in Unity.
+==== Unity Files ====
+=== Attachment Tools ===
+The Unity Team developed a set of very useful tools to attach elements to a deforming mesh in realtime. You can implement those tools in your own project by getting them [[https://github.com/Unity-Technologies/com.unity.demoteam.digital-human| here]].
+First an empty dataset is created in the Assets Window. (right click -> Digital Human -> skin attachment data )
+Then in the outliner you select the object you want to have attached to the deforming mesh.
+Add a 'Skin Attachment Target'-Script to it's Inspector and specify the dataset you just added.
+Select the mesh driving the deformation, add a 'Skin Attachment'-Script to its inspector and specify the targets. (This only works if you insert the script after the 'Skinned Mesh Renderer'/'Mesh Renderer' )
+Go back to the inspector of the target and fill in the dataset with the required mesh information.
+As for now these tools only work with meshes being deformed by the GPU.
+=== Shading & Rendering ===
+The skin and eyes are using a dedicated shader connected to a set of dedicated scripts.
+The eyes can easily be customized to fit the needs of the required reference model.
+We're still looking into the skin shader, particularly the system they applied to blend 82 different textures based on the faceshape.
