AI-generated overview

Guides creation of Hytale character and prop models and animations in Blockbench using Hytale plugin MCP tools.

What it does
This skill documents how to build Hytale models and animations in Blockbench through the Hytale plugin's MCP tools. It covers format and validation checks, cube properties such as shading mode, double-sided faces and stretch, 2D quads, attachment pieces, and animation visibility keyframes and loop modes. It also lists the plugin's resources, prompts, Hytale formats, constraints and step-by-step workflows for characters, weapon attachments and weapon-draw animations.
When to use it
Use it when working with Hytale character or prop formats, creating attachment pieces, setting shading modes, using quads, or animating with visibility keyframes. It applies when the Hytale Blockbench plugin is installed and the task involves Hytale model or animation authoring.
Requirements
Requires the Hytale plugin installed in Blockbench and access to the plugin's MCP tools, resources and prompts. It ships no scripts; it is instructions only.

Constraints

  • Max nodes: 255 (groups + extra cubes)
  • Animation FPS: 60
  • UV size: Must match texture resolution

Shading Modes

ModeEffect
standardNormal lighting (default)
flatNo lighting/shadows
fullbrightAlways fully lit (emissive)
reflectiveReflective material

Quick Start

Check Format

hytale_get_format_info# Returns: formatType, blockSize, nodeCount, features

Validate Model

hytale_validate_model# Returns: valid, nodeCount, issues

Cube Properties

Set Shading Mode

hytale_set_cube_properties: cube_id="crystal", shading_mode="fullbright"

Enable Double-Sided

hytale_set_cube_properties: cube_id="cloth", double_sided=true

Set Stretch

hytale_set_cube_stretch: cube_id="arm", stretch=[1.2, 1.0, 1.0]

Quads (2D Planes)

Create single-face planes:

hytale_create_quad: name="leaf",  position=[0, 16, 0],  normal="+Y",  # +X, -X, +Y, -Y, +Z, -Z  size=[8, 8],  double_sided=true

Attachments

List Attachments

hytale_list_attachments

Mark as Attachment Piece

hytale_set_attachment_piece: group_name="hand_right", is_piece=true

This bone will attach to hand_right on the base model.

List Attachment Pieces

hytale_list_attachment_pieces

Animation

Visibility Keyframe

Toggle bone visibility during animation:

hytale_create_visibility_keyframe:  bone_name="weapon_sheathed",  time=0.5,  visible=false
hytale_create_visibility_keyframe:  bone_name="weapon_drawn",  time=0.5,  visible=true

Set Loop Mode

hytale_set_animation_loop: animation_id="walk", loop_mode="loop"hytale_set_animation_loop: animation_id="attack", loop_mode="once"hytale_set_animation_loop: animation_id="death", loop_mode="hold"

Common Workflows

Create Character Model

# 1. Create project (use bedrock format, Hytale format activates automatically)create_project: name="goblin", format="bedrock"
# 2. Build bone hierarchyadd_group: name="root", origin=[0, 0, 0]add_group: name="body", parent="root", origin=[0, 12, 0]add_group: name="head", parent="body", origin=[0, 24, 0]add_group: name="arm_left", parent="body", origin=[6, 22, 0]add_group: name="arm_right", parent="body", origin=[-6, 22, 0]add_group: name="hand_right", parent="arm_right", origin=[-8, 16, 0]
# 3. Add geometryplace_cube: elements=[{name: "torso", from: [-4, 12, -2], to: [4, 24, 2]}], group="body"
# 4. Set Hytale propertieshytale_set_cube_properties: cube_id="eyes", shading_mode="fullbright"
# 5. Validatehytale_validate_model

Create Weapon Attachment

# 1. Create attachment structureadd_group: name="hand_right", origin=[0, 0, 0]
# 2. Add weapon geometryplace_cube: elements=[{name: "blade", from: [-0.5, 0, -0.5], to: [0.5, 24, 0.5]}], group="hand_right"
# 3. Mark as attachment piecehytale_set_attachment_piece: group_name="hand_right", is_piece=true
# 4. Add glowing effecthytale_set_cube_properties: cube_id="rune", shading_mode="fullbright"

Animate Weapon Draw

# Start with sheathed weapon visiblehytale_create_visibility_keyframe: bone_name="sword_sheathed", time=0, visible=truehytale_create_visibility_keyframe: bone_name="sword_drawn", time=0, visible=false
# At draw point, swaphytale_create_visibility_keyframe: bone_name="sword_sheathed", time=0.3, visible=falsehytale_create_visibility_keyframe: bone_name="sword_drawn", time=0.3, visible=true

Tips

  • Always run hytale_validate_model before export
  • Keep node count under 255
  • Use stretch instead of fractional cube sizes
  • Set group origins at joint/pivot points
  • Use fullbright shading for glowing elements
  • Mark equipment bones as is_piece=true for attachments
  • Use visibility keyframes for state changes (weapons, damage)
  • Animation runs at 60 FPS (time 1.0 = 60 frames)
