Changelog

This is a high-level changelog for what has been worked on so far.

At the moment, this module doesn't have a distinct release schedule, so this changelog follows Godot's version numbers and binary releases. Each version mentionned here should have an associated Git branch containing features at the time of the version. Backports aren't usually done so far, but PRs are welcome if it's necessary.

Semver is not yet in place, so each version can have breaking changes, although it shouldn't happen often.

master

  • General

    • Introduction of Voxel Server, which shares threaded tasks among all voxel nodes
    • Voxel data is no longer copied when sent to processing threads, reducing high memory spikes in some scenarios
    • Added a utility class to load .vox files created with MagicaVoxel (scripts only)
    • Voxel nodes can be moved, scaled and rotated
    • Voxel nodes can be limited to specific bounds, rather than being infinitely paging volumes (multiples of block size).
    • Meshers are now resources so you can choose and configure them per terrain

  • Editor

    • Streaming/LOD can be set to follow the editor camera instead of being centered on world origin. Use with caution, fast big movements and zooms can cause lag
    • The amount of pending background tasks is now indicated when the node is selected
    • Added About window

  • Smooth voxels

    • Shaders now have access to the transform of each block, useful for triplanar mapping on moving volumes
    • Transvoxel runs faster (almost x2 speedup)
    • The SDF channel is now 16-bit by default instead of 8-bit, which reduces terracing in big terrains
    • Optimized VoxelGeneratorGraph by making it detect empty blocks more accurately
    • Added SdfSphereHeightmap and Normalize nodes to voxel graph, which can help making planets

  • Blocky voxels

    • Introduced a second blocky mesher dedicated to colored cubes, with greedy meshing and palette support (scripts only)
    • Replaced transparent property with transparency_index for more control on the culling of transparent faces
    • The TYPE channel is now 16-bit by default instead of 8-bit, allowing to store up to 65,536 types (part of this channel might actually be used to store rotation in the future)

  • Breaking changes

    • VoxelViewer now replaces the viewer_path property on VoxelTerrain, and allows multiple loading points
    • Defined COLOR channel in VoxelBuffer, previously known as DATA3
    • VoxelGenerator is no longer the base for script-based generators, use VoxelGeneratorScript instead
    • VoxelStream is no longer the base for script-based streams, use VoxelStreamScript instead
    • Terrain nodes no longer produce meshes based on the voxel data. Instead they use the mesher assigned to them.
    • SDF and TYPE channels have different default depth, so if you relied on 8-bit depth, you may have to explicitely set that format in your generator, to avoid mismatch with existing savegames

  • Fixes

    • C# should be able to properly implement generator/stream functions

  • Known issues

    • VoxelLodTerrain does not entirely support VoxelViewer, but a refactoring pass is planned for it.

godot3.2.3 - 08/09/2020

  • General

    • Added per-voxel and per-block metadata, which are saved by file streams along with voxel data
    • StringName is now used when possible to call script functions, to reduce overhead
    • Exposed block serializer to allow encoding voxels for network or files from script
    • Added terrain methods to trigger saves explicitely
    • The module only prints debug logs if the engine is in verbose mode
    • VoxelTerrain now emit signals when blocks are loaded and unloaded

  • Editor

    • Terrain nodes now render in the editor, unless scripts are involved (can be changed with an option)

  • Blocky voxels

    • Added collision masks to blocky voxels, which takes effect with VoxelBoxMover and voxel raycasts
    • Added random tick API for blocky terrains
    • Blocky mesh collision shapes now take all surfaces into account

  • Smooth voxels

    • Added a graph-based generator, dedicated to SDF data for now

  • Fixes

    • Fixed crash when VoxelTerrain is used without a stream
    • Fixed Voxel.duplicate() not implemented properly
    • Fixed collision shapes only being generated for the first mesh surface
    • Fixed VoxelTool truncating 64-bit values

(no branch) 27/03/2020 Tokisan Games binary version

  • General

    • Optimized VoxelBuffer memory allocation with a pool (best when sizes are often the same)
    • Optimized block visibility by removing meshes from the world rather than setting the visible property
    • Added customizable bit depth to VoxelBuffer (8, 16, 32 and 64 bits)
    • Added node configuration warnings in case terrain nodes are wrongly setup
    • Implemented VoxelTool for VoxelBuffers
    • Added VoxelStreamNoise2D
    • Added blur option in VoxelGeneratorImage
    • Generators now all inherit VoxelGenerator

  • Blocky voxels

    • Blocky voxels can be defined with a custom mesh, sides get culled automatically even when not a cube
    • Blocky voxels can have custom collision AABBs for use with VoxelBoxMover
    • The 3D noise generator now works in blocky mode with VoxelTerrain
    • Blocky voxels support 8 bit and 16 bit depths

  • Smooth voxels

    • Implemented Transvoxel mesher, supporting transition meshes for seamless LOD. It now replaces DMC by default.
    • Heightmap generators now have an iso_scale tuning property which helps reducing terracing

  • Fixes

    • Fixed dark normals occasionally appearing on smooth terrains
    • Fixed Transvoxel mesher being offset compared to other meshers
    • Fixed stuttering caused by ShaderMaterial creation, now they are pooled
    • Fixed cases where VoxelLodTerrain was getting stuck when teleporting far away
    • Fixed a few bugs with VoxelStreamBlockFiles and VoxelStreamRegionFiles

  • Breaking changes

    • Removed channel enum from Voxel, it was redundant with VoxelBuffer
    • Renamed VoxelBuffer.CHANNEL_ISOLEVEL => CHANNEL_SDF
    • Removed VoxelIsoSurfaceTool, superseded by VoxelTool
    • Removed VoxelMesherMC, superseded by VoxelMesherTransvoxel
    • Replaced VoxelGeneratorTest by VoxelGeneratorWaves and VoxelGeneratorFlat

godot3.1 - 03/10/2019

Initial reference version.

  • Support for blocky, dual marching cubes and simple marching cubes meshers
  • Terrain with constant LOD paging, or variable LOD (smooth voxels only)
  • Voxels editable in game (limited to LOD0)
  • Various simple streams to generate, save and load voxel terrain data
  • Meshers and storage primitives available to use by scripts
