    I just wanna know how can I create a shader lod in Shader Graph . Because I can do it in original shader file easily by adding a subshader.So What do I need to do?

    If you mean the Shaderlab syntax of giving a subshader a LOD value (or even explicitly creating subshaders in the graph), that does not currently exist in Shader Graph. You can handle your own shader complexity by using keywords to control more expensive parts of the shader or make sure LODGroups are used on renderers to have better control of when more expensive shaders are used in a project.

    alright then. I got another few questions. can I get cull mode property from material with Shader Graph? or I need to duplicate a Shader Graph for different Cull mode property? (same question with Blend Option property) and if so,are these two shader graph compiled to just one shader because they exactly have the same vertex and pixel shaders.

    bump
    and how do i set the material quality at runtime? what's the cost of that? (as cheap as LOD is my guess)
