ArmorStand

Models are loaded from files placed in a models directory, and the player chooses one in the mod settings. Supported formats include glTF, VRM, PMD and PMX models, along with VMD animation files, which can be imported and controlled through an in-game animation screen opened with the K key. Bedrock-format entity models that are unencrypted and not zipped can be rendered as well, which lets the mod work with the YSM models that use that layout.

In multiplayer, the mod synchronizes the displayed model between players by using a hash of each model file. Renaming a model or moving it into a subdirectory does not break synchronization, and changes to a model's content are picked up by other players. Model files themselves are not transferred, so the server and each player need the same mod installed for other players to see the chosen model. The client can also render instanced draws for many models at once and works with shader packs through the renderer config.

The mod is built on BlazeRod, a library written in Kotlin and Java that supplies the rendering layer and does not rely on a native library, so it runs across platforms. Fabric API is required on Fabric, Fabric Language Kotlin is required on Fabric, and Kotlin for Forge is required on NeoForge. Mod Menu is optional. ArmorStand is open source under the GNU Lesser General Public License v3.0 or later, and the source code and issue tracker are public. The mod is in early development, and only the 1.21.8 build is maintained; earlier 1.21.5 – 1.21.7 builds receive no new features. Snapshot builds are published.
