Tessellation and instancing

Hi,

I'm having a really hard time with a surface shader that has tessellation. This shader is meant to be rendered on the magic leap device where I'm using single pass instanced rendering.

After some work I tracked the issue to the instancing. It looks like tessellation and instancing can't be enabled at the same time.

After I added #pragma noinstancing to the shader, it compiled. However, since I'm using single pass instanced on the device, the shader only renders to one eye.

Is there anything that I can do to overcome this issue?

I'm using Unity 2019.2.3f1

Thanks in advance.
