- Description:
- MudBun is a real-time volumetric VFX mesh tool that can also be used for volumetric modeling. It procedurally generates meshes from non-destructive 'brushes' that define shapes, distortion, and surface modification. MudBun is intended for localized VFX, but it can also be used for volumetric modeling and provides a convenient auto-rigging feature. Locked meshes, including auto-rigged ones, can be exported using Unity's official FBX exporter package. There are various render & meshing modes available with different styles & characteristics. Supported meshing modes include: marching cubes (balanced), dual quads (faster & stylized), surface nets (can blend to/from dual quads), and dual contouring (slower, excels at preserving sharp features, can blend to/from dual quads). MudBun can be used to create organic-looking meshes, which makes it a great combo with Boing Kit, a tool for producing organic bouncy effects. MudBun is customizable. Users can extend the framework to create custom brush shapes, distortion brushes, modifier brushes, and shaders. It is also possible to define custom rigging logic for the auto-rigging feature. Using a special data representation, MudBun frees users from worrying about the constraints of a finite voxel grid when working within typical game settings.
- Technical Details:
- MudBun supports Unity 2021.3 (LTS), 2022.3 (LTS), and 6 (LTS) with built-in render pipeline, URP, and HDRP. It is only under active development, maintenance, and testing on Windows. Non-Windows platforms are not guaranteed to run MudBun and support for them is limited. WebGL is not supported due to its lack of compute shader capabilities. MudBun uses compute shaders and requires dedicated GPUs. It is not recommended to target hardware with integrated GPUs, unless MudBun is only used at edit-time to build meshes to be exported or locked at run-time. MudBun has various render & meshing modes, including marching cubes, dual quads, surface nets, and dual contouring. It also supports brush operators like union, subtract, intersect, dye, cull inside, cull outside, and no-op. Dynamic voxel density, 2D Mode, mesh collider generation, mesh locking & auto-rigging, mesh auto-smoothing, automatic vertex welding of generated mesh, SDF texture generation, smooth corners for dual contouring, and custom Unity shader graph nodes are also supported. MudBun has a borderless voxel workspace and GPU memory budgeting & auto adjustment.
