NOTICE: Importing The Package & Building Executables When updating from older versions of MudBun, DELETE the entire MudBun folder before re-importing from a newer package. File structures might have changed, and directly re-importing a new package on top of an existing one could cause unexpected issues. Also, there are folders specific to render pipelines: Built-In RP , URP , and HDRP . They exist in the folders MudBun/Examples and MudBun/Shader/Render . Only import the folders that are specific to the current render pipeline and leave out the rest. It wouldn’t matter in play mode in editor, but can cause errors when building executables. DO NOT move the MudBun root folder away from the Assets root folder, as this is a necessary trade-off for not having to force users to place custom shaders in the same folder as MudBun’s built-in shaders. NOTICE: Bugs in Unity’s Package Manager At the time of writing, versioning and caching of asset packages in Unity’s package manager are buggy. The local copy of MudBun can be out of date even if the package manager displays the asset’s version as up to date. To check the actual version of the local copy of MudBun, create and select a renderer, and the version will be shown in the inspector panel. If the displayed version is different from what the package manager shows, then a manual deletion of local package cache is required. To do so, navigate to “C:\Users\(username)\AppData\Roaming\Unity\Asset Store-5.x\Long Bunny Labs” and delete the cache for MudBun. NOTICE: Compatibility with HDRP 10.0.0+ If HDRP 10.0.0+ is used (Unity 2020.2+ by defualt), a manual import of compatibility packages is required. Compatibility packages are located in the “MudBun/Compatibility” folder. NOTICE: Click Selection Later Unity versions have disabled click selection on invisible gizmos if gizmo drawing is disabled in the Unity editor. In this case, gizmos drawing must be enabled for click selection to work. NOTICE: Examples There are different examples in each render pipeline�s example folder.
