Hello, thank you for getting in touch!
Tested our Tessellation sample in a new 2017.4 project with the latest ASE and it seems to be working as expected.
Could you please confirm if you have "Enable GPU Instancing" toggled OFF in your material inspector?
This error might be related to the way Tessellation is handled in Unity, since we use its technique in ASE.
In any case, disabling it and compiling the shader should effectively clear the error, please let me know if this is the case, thanks!
