Hytale 3D model generator: from a description to a native .blockymodel

Hytale models are made of boxes and flat quads, each with a position, an orientation and a texture layout that says which part of the image covers which face. They are stored in the .blockymodel format and listed in an asset pack with a manifest. Modelling one by hand in Blockbench is precise work: placing every box, unwrapping every face and painting the pixel art.

The generator does that first pass from your description and hands you a pack that follows Hytale's layout:

Your description is first turned into a structure: named parts, their sizes and their positions, the way a modeller would block out a shape. Every face is then given its own area of the texture at one consistent density, and the materials are painted into those areas as pixel art. This is the same pipeline that produces our Minecraft 3D models, so the shapes are clean and the textures stay sharp.

For Hytale, the result is converted at export time. A Minecraft block is 16 units and a Hytale block is 32, so the model is rescaled; each box keeps its texture region and uses Hytale's stretch value to reach its real size, which is how Hytale maps one texture pixel per unit. Rotations become the quaternions Hytale stores, and named groups become nodes you can rig in Blockbench.

Download the zip from the project's download panel and place it in your world's or server's mods folder. In Hytale's Asset Editor the model appears under Items, Spaleforce, Generated, where you can assign it to an item, a block or an NPC. To refine the shape or animate it, open the .blockymodel in Blockbench with the official Hytale plugin: the boxes, names and texture are all editable.

You can also keep iterating on our side first. Ask the AI to make the blade longer, change a color or add a detail, check the result in the 3D viewer, then export again: the pack is always built from the current version of the model.

It works best on objects with a clear silhouette: weapons and tools, furniture and decoration, food, plants, lamps, chests and small creatures. Characters keep their named bones so they are ready to animate, but animations themselves are not exported to Hytale yet.

Connecting a model to gameplay is not automatic: an item, block or NPC definition decides how it is used, and that is done in Hytale's Asset Editor. If you need custom behaviour around the model, the Hytale plugin generator writes the server side.
