Hello Spacebar, thank you for getting in touch!
We don't have a specific sample to provide a basic starting point for a skin shader at this time, perhaps somewhere in the future we'll try to cook up something nice!
I would recommend that you try asking other community members in the
ASE Unity thread, since this forum is more geared towards technical support and ,as a result, most community members resort to the Unity forum instead in order to exchange tips, questions and answers.
Please let us know if you have any further questions, thanks!
