    Hi.

    is it possible to do a double-sided shader with an offset that can be set using properties?
    I can move the vertex position in the vertex part of the shader but the "Is Front Face" node is only for pixel shader so I can't just move one side.

    If I understand correctly, I don't think you can achieve that without making copies of the vertices.

    In built-in, I can create a shader with two passes, one with the cull front and the other with the cull back. One of the passes can move the vertex with a given offset.
