    Does it mean that we can access the "unity_InstanceId", in shadergraph?

    Yeah after having turned off instancing on all our materials it looks like re-activating them works

    Fixed! After getting 7.1.5, then re-importing all assets, the error has stopped showing. I'm not sure if this is how your supposed to get the fix to work, but it worked for now.

    Just grabbed the 7.1.5 update, still getting " redefinition of 'unity_Builtins2Array'" from shadergraph shaders

    So I am looking at our project with URP 7.1.5 and still getting this issue, using 2019.3b10

    Glad this is being fixed in 7.1.3, thank you for moving that up! Is there an ETA for that release?

    When will 7.1.3 be available ? Is there a roadmap for packages as well?

    The fix has been backported to 7.1.3 as well, which will be available for 2019.3.

    Can someone re-open this bug or make a re-submission? I am not sure if the comments on a fixed bug are ever read.

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