When both the Universal RP (7.1.2 or 7.1.1) and the Cinemachine 2.4.0 packages are installed I get these two errors: Assembly with cyclic references detected (Packages/com.unity.render-pipelines.universal/Runtime/Unity.RenderPipelines.Universal.Runtime.asmdef) Assembly with cyclic references detected (Packages/com.unity.cinemachine/Runtime/com.unity.cinemachine.asmdef) There are indeed references to the URP in the Cinemachine assembly definition and vice versa. But the references can't simply be removed, as either package requires them. The project will still compile. However, having both of these packages installed unsurprisingly breaks lots of things. Depending on the order in wich you install the URP or Cinemachine, you will either get a Cinemachine dropdown menu or an Edit > Render Pipeline menu, but not both. If you uninstall the URP, then install Cinemachine, and then re-install the URP, you can get Cinemachine working. But you will lose the project materials and the Render Pipeline is then also broken, as you will be unable to access its menu and upgrade the materials. So in essence: The most recent versions of the URP and Cinemachine simply do not play nice together, despite the official word being that they are meant to be compatible. Tested on 2019.3.0b7 and 0b9. Is this already known? Any chance there's an upcoming fix for either Cinemachine or the Universal RP?
