VOXELBRIDGE

VoxelBridge

VoxelBridge is a client-side NeoForge mod that exports Minecraft blocks, fluids, block entities, and modded blocks to glTF with full biome color (tint) support, ready for DCC softwares such as Blender, Maya, Cinema4D, and other tools.

Features

  • Export blocks, fluids, and block entities
  • Accurate biome tinting (grass, leaves, water, vines, etc.)
  • Individual textures or UDIM-style packed atlas (tile size up to 8192)
  • Choose centered or world-space coordinates
  • Adjustable atlas size and export thread count
  • Timestamped export folders (export/<timestamp>/)
  • Supports most modded blocks, resource packs, and custom models
  • Now supports CTM! (Continuity only）

Usage

Hotkeys

  • pos1 — Numpad 7
  • pos2 — Numpad 9
  • export — Numpad 5
  • clear — Numpad 0

Commands (/voxelbridge)

pos1, pos2, info, clear,
atlas [individual|atlas],
atlassize <128–8192>,
coords [centered|world],
threads <1–32>,
export.

Export Output

Files are saved in:

export/<timestamp>/gltf/

Texture locations

Texture Path
Biome tint colormap textures/colormap
Block/terrain atlas textures/atlas
Block entity atlas textures/blockentity_atlas

Biome Tinting (Important)

VoxelBridge generates a colormap texture to reproduce Minecraft biome colors.

To display correct colors in Blender or other DCCs:

  1. Use base atlas UV for the main texture
  2. Use second UV channel for the colormap
  3. Multiply (BaseColor × Colormap)
  4. Set all sampler filters to Nearest / Closest

Example shader setup:

shader nodes

Colormap: textures/colormap
Atlas: textures/atlas
Block entity atlas: textures/blockentity_atlas

Compatibility Notes

Rendering / performance mods

Avoid mods that modify rendering pipelines, such as:

  • Sodium
  • Iris
  • OptiFine
  • Embeddium
  • Canvas

They may alter tint pipelines or texture sources → causing incorrect exports.

Modded blocks & resource packs

VoxelBridge supports:

  • Most modded blocks
  • Most resource packs
  • Custom models

but compatibility is not guaranteed for every mod.

Resource pack resolution rule

Atlas tile size must be larger than the resource pack texture resolution.
Example for a 256× pack:

/voxelbridge atlassize 512

PBR support

Currently exports only Albedo (base color).
PBR maps (normal/roughness/metallic/etc.) are not yet supported.
