Hello,
I ran into the issue that I get shader compile-errors because of the redefinition of unity_Builtins2Array in UnityInput.hlsl. I found this bug on the issue tracker: Unity Issue Tracker - [UniversalRP] Shader compilation error when using GPU instancing.
It seems this bug is not only valid for GPU instancing and the question is if the fix gets backported to the available 7.1.2 version.
This problem is currently blocking me to upgrade to 2019.3, because this error occurs then to my shader graph shaders which are worked perfectly before the upgrade.
Any plans about this?
