Hello,
We are having a problem very similar to one previously posted here: Kernel 'KSampleCopy4_1_x_8' not found under Unity 2018.3
We’re using Unity 2018.3.3f1 with HDRP 4.9.0.
The problem is that we keep having this “Kernel ‘KSampleCopy4_1_x_8’” errors popping up in our standalone builds for our several target platforms (PS4, XboxOne, Switch), and nothing except the UI is being rendered in the scene.
The difference from the previously linked post is that it doesn’t only happen upon update for us, but instead, it may or may not happen during/after the build process. For instance once the current build is finished, and works, the very next one, without any changes made to it may end up having the this problem in it.
Re-importing packages does indeed help, but since we’re working with multiple platforms, we want to be able to use automated build tools such as TeamCity, and that’s where it becomes a real problem for us.
We weren’t sure if developers are fully aware of this issue, or if there’s a fix for it scheduled sometime in the future, thus we decided to make a separate post about it here.
