Lumina's custom: 3D Models

The mod loads real 3D assets into the game and keeps the skeleton, weights, surface materials, shape keys and animation data of each file. Models can come straight from standard 3D pipelines, so an asset does not have to be rebuilt as cubes. FBX and GLB are handled natively, including built-in animation systems, and MMD models are supported through PMX and PMD files with VMD animation playback.

Everything runs through presets. A preset is not a model file but a full package: it holds the 3D asset, its render configuration, material, scale, position and rotation tweaks, and optional physics for MMD models only. Animation files are kept separate from gameplay logic, and each preset maps animation clips to states such as walk, sprint, jump, idle, swim and attack. Player presets follow the actual player state, block presets swap animations by redstone level, and entity presets switch clips by movement and combat.

Installation needs Fabric. Only players need the mod, while a server can run without it. The mod is published for 1.21.4 and 26.2, and the latest Fabric file is 1.0.0 for 26.2. The code is released under the MIT License but is not open source.
