MudBun: Volumetric VFX & ModelingUnityAssetStore

Version 1.3.30（current）

Released: Sep 20, 2021

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 The local copy of MudBun can be out of date even if the package manager displays the asset's version as up to date.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. Be sure to check each example's out under its corresponding render pipeline. Version 1.3.30 - Add elongation to brushes: cylinder (scale XZ), cone (scale XZ), torus (parameter), simple curve (parameter).

Version 1.0.22 - New brush operators: Cull Inside & Cull Outside. - Options to match splat normals & shadows to splat camera facing. - Expose MudRendererBase.RenderMaterialPropertyBlock. - Decal render mode renders box proxy instead of fully-computed mesh. - Fix missing pixels along mesh triangle seams in dual meshing modes. Version 1.0.21 - Add assembly definitions. - Fix shader compatibility with HDRP 10.0.0+ (see notes above). - Fix moving other objects (e.g. camera) in editor triggering re-compute. - Fix missing shader node for decal shaders. - Fix forcing convex collider unconditionally generating rigid bodies. - Fix the last-frame state of a stopped particle system not being reflected. - Fix potential empty names when saving mesh assets. - Fix cross-renderer decal interference due to undesired depth writes.

Version 0.9.19b - New advanced splats option: original normal blend. - Add un-cached Perlin noise type to noise volumes in case resolution artifacts from Cached Perlin noise type are undesirable. - Tweak particle self blend pops. - Bump max voxel density to 100 (be careul about performance though). - Fix exception upon locking mesh in mesh renderer mode. Version 0.9.18b - New preset mesh render materials: Alpha-Blended Mesh (for 2D mode), Outline Mesh (for 2D mode), SDF Ripple Mesh (for 2D mode). - Option to force convex collider without having to create rigid bodies. - Generated mesh is automatically welded if no UV generation is specified (takes up less memory/disc space & friendly to mesh simplification tools). - Fix render bounds that caused false positive camera culling. - Fix camera framing of empty renderers and brushes. - Fix particle pops as they die off. - Fix exception upon disabling and re-enabling renderers.
