+ | |||
+ | 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:// | ||
+ | |||
+ | 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' | ||
+ | |||
+ | Select the mesh driving the deformation, | ||
+ | |||
+ | 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 === | === Shading & Rendering === | ||
+ | The skin and eyes are using a dedicated shader connected to a set of dedicated scripts. | ||
- | ===== VR ===== | + | The eyes can easily be customized to fit the needs of the required reference model. |
- | * 2019 [[https://www.youtube.com/watch? | + | We're still looking into the skin shader, particularly the system they applied to blend 82 different textures based on the faceshape. |
