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 The local copy of MudBun can be out of date even if the package manager displays the asset's version as up to date.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 1.4.46 - Fix error on unsafe code in SdfEval.cs. Version 1.4.35 - Add links to online scripting API documentation to Tools > MudBun menu and start screen (online documentation still WIP). - Fix asynchornous Sdf.EvaluateSdfAndNormal not running. - Signature change to CPU-based evaluation functions: SDF and normal evaluation now both output Sdf.Result values (requires potential update to user code). - Fix Unity FBX Exporter not properly exporting metallic and emission by moving them to UV3 and UV4 (old locked meshes need to be re-locked for the new locked mesh shader to work properly). - Fix missing screen space ambient occlusion in URP10+. - Add options to generate UVs for texture (UV1) and light map (UV2) when locking meshes in mesh renderer mode. - Remove GC.Alloc calls from enum-int conversions. - Cache material validation to improve play mode performance in editor. Version 1.4.34 "Raycasts" - CPU-based computations: SDF evaluation, gradient evaluation, raycasts, snapping to surface. - Raycast-based click selection by default. Gizmo-based click selection is still an option on renderers. - Burst is now required to use raycast-based click selection & CPU-based computations. - MudMaterial.IntWeight is renamed to MudMaterial.TextureWeight to better reflect its use in default shaders (users can still do whatever they want with it in custom shaders). - Add noise modifier brush. - Add MUDBUN_FAST_ITERATION define in CustomBrush.cginc for even faster iteration. - Only fill in necessary default values for render materials (improves build time by skipping compilation of unused render material shaders). - Fix edge cases of voxel edges perfectly lining up with zero isosurface. - Fix distortion brushes only being applied to the first brush group and not subsequent brush groups. - New HDRP example: Raycasts Version 1.3.33 - Materials are now sampled at voxel centers, rather voxel corners, for more reliable/predictable results in the Dual Quads meshing mode. - Fix broken simple curve when all control points are colinear. - Remove decompressed examples accidentaly included in previous update. Version 1.3.32 - Add render material mode to renderer for controlling how render materials are copied. - Add MudRenderer.MarkMaterialDirty() for manually picking up changes in render material at run-time when using the static render material mode. - Fix incorrect imports of HDRP 10 compatibility package on older HDRP versions. - Fix warning when used with Unity timeline. Version 1.3.31 - Add start screen. Examples are now optionally imported via the start screen. - Automated import of packages specific to current render pipeline and its version. - Fix negative splat normal shift. - Fix missing meshes from particle system brushes when locking while the particle emitters are paused. - Fix URP object normals used as world normals. Version 1.3.30 - Add elongation to brushes: cylinder (scale XZ), cone (scale XZ), torus (parameter), simple curve (parameter). May change existing shapes (if that happens, set cylinder/cone XZ scale or torus Y scale to 1.0). - Add setters to MudRenderer's master material properties. - Fix unconditional inclusion of bone weights when locking meshes with vertex welding. - Fix renderer's Always Draw Gizmos option not drawing brush gizmos. - Improve bone weighting of full curve brushes. Version 1.3.29 "Claymation" - Add tangent outputs to shader graph nodes. - Add normal map support to default mesh shaders & stopmotion mesh shader. - Add compute mode for controlling compute frequencies. - New preset mesh render materials: Clay Mesh, Claymation Mesh. - Fix texture tiling and offsets for URP & HDRP. - Fix bloated bounds for intersection brushes that could unnecessarily exhaust voxel chunk budget. - Fix decal render mode causing Unity to hang. - New HDRP examples: Claymation Terrain & Water, Claymation Fire, Claymation Water Splash. Version 1.2.28 "Ray-Traced Voxels" - New render mode: Ray-Traced Voxels (experimental / URP only). - Collider mesh asset generation. - Add collider surface shift option. - Vertex welding supported when UV generation is turned on. - Duplicate utility button on brushes. - New simple curve properties: control point radius, smooth step blend. - Locked standard meshes without asset generation are also optimized for rendering. - Remove gizmo icons to declutter scene view. - Move ASE nodes under MudBun category. - Fix broken full curve brush when away from world origin. Version 1.0.23 "Symmetry" - Symmetry modes for solid brushes: Flip X, Mirror X, Flip Mirror X. - Fix occasional missing brushes. Version 1.0.20 "Decal" - New render mode: Decal. - New preset decal render materials: Decal Paint, Decal Darken, Decal Lighten. - Curve noise threshold core bias. - Curve noise twists. - Add option to turn on/off vertex welding upon locking mesh in mesh renderer mode. - Remember materials when unlocking locked meshes. - SDF texture generation (can be used for collision against GPU particles from Unity's VFX graphs). - New Built-In RP example: Decals. - New HDRP examples: GPU Particle Collision, Vortex. Version 0.9.15b "2D Mode" - 2D mode. - Surface Shift parameter. - Force Evlauate All Brushes option. - New Built-In RP examples: 2D & 3D Spin Puff Comparison, 2D Sci-Fi Grid, 2D SDF Visualization. - Improve build time by skipping compilation of unused shaders.
