Question Can't transfer a property to GPU instancing + tessellation shader.

Hi guys!
Is it possible for a Standard shader to have Tessellation + GPU Instancing?

 

Is it possible to have a shader with instancing and tessellation? Technically, yes.

Can you do this with Surface Shaders? No.

Unity's Surface Shaders and the code it generates when you try to use tessellation wasn't written to work with instancing, so it generates code that will fail to compile once instancing is enabled. Unfortunately you'd have to write the shader code entirely by hand to get tessellation to work as you do need the instanced ID to be passed through multiple shader stages.
