Hello,
I wanted to try SBP again and it is not located in the package manager, even when showing the preview packages in 2019.1.0f1. Adding it manually to the manifest.json yields the following error:
Was the package discontinued or renamed?
EDIT: Nevermind, solved! The version string should be e.g. "com.unity.scriptablebuildpipeline": "1.3.5-preview"
.
However, still do not know why it didn’t show up in the package inspector, at all?
