    In 2019.3 I can not get Shader Graph 8.0.0. Will they be a fix for 7.1.2?

    We really need a fix for this in 2019.3 Same error with or without GPU instancing

    What release will this get fixed in? Is 8.0.0 Unity 2020 only as this really needs back porting to 2019.3.0

    Will that be available for 2019.3?

    Same issue - I get the error regardless, but shader breaks when enabling GPU instancing

    I'm getting this exact error with a ShaderGraph, regardless of GPU Instancing.
    I'm working on Unity 2019.3.0b6, URP 7.1.2, Android + Oculus Quest

    I'm getting this with a Shader Graph shader, but only when I enable GPU Instancing.
