Design a model or texture

Minecraft Creator Tools can build a mob model and its texture from a JSON design, save both into the resource pack, and return a preview image you can look at. Iterate on the design until it matches what the user asked for, then connect the mob to it: the tool writes files but doesn't update the content that should use them. For items and blocks, this skill covers flat textures (icons and block faces) only.

Custom 3D block shapes and 3D held items need extra wiring (block minecraft:geometry and material instances, item attachables) that this skill doesn't cover yet. If the user asks for one, say so and offer a textured regular block or a flat item icon instead.

1. Find the target

• Existing content: find its identifier and pack. For a mob, open resource_packs/<pack>/entity/<id>.entity.json and note geometry.default and textures.default. For an item icon or block texture, note its path in textures/item_texture.json or textures/terrain_texture.json and skip to step 5.
• New content: create it first with create-mob, create-item, or create-block, then come back here.

2. Start from a template (mobs)

Call getModelTemplates with the closest mob templateType (for example humanoid, small_animal, large_animal, bird, insect, golem, wizard, ghost, robot; the tool lists them all). Templates have Minecraft-correct proportions, and adjusting one is far more reliable than writing geometry from scratch.
