Creating Materials

Use this skill to give objects visual identity through colors, textures, and material properties.

Trigger Phrases

•"color", "colored", "red", "blue", etc.
•"shiny", "metallic", "glossy"
•"transparent", "glass", "see-through"
•"glowing", "emissive", "neon"
•"texture", "wood", "stone", "metal"

When to Apply (Automatically)

Apply materials when:

•Creating any visible object (give it identity)
•User describes a look ("red enemy", "golden coin")
•Objects need visual distinction (player vs enemy)
•Effects need glow (lasers, power-ups)

Implementation

Creating Materials via MCP

code

manage_asset action="create"
  path="Assets/Materials/MyMaterial.mat"
  asset_type="Material"
  properties={"color": [R, G, B, A]}

Applying to Objects

code

manage_gameobject action="set_component_property"
  target="ObjectName"
  component_name="MeshRenderer"
  component_properties={"MeshRenderer": {"sharedMaterial": "Assets/Materials/MyMaterial.mat"}}

Material Types

Matte (Default)

code

color: [R, G, B, 1]
metallic: 0
smoothness: 0.2

Shiny/Glossy

code

color: [R, G, B, 1]
metallic: 0
smoothness: 0.8

Metallic

code

color: [0.8, 0.8, 0.8, 1]
metallic: 1.0
smoothness: 0.7

Transparent/Glass

code

color: [R, G, B, 0.3]  // Low alpha
renderingMode: Transparent
metallic: 0
smoothness: 1.0

Glowing/Emissive

code

color: [R, G, B, 1]
emission: [R*2, G*2, B*2, 1]  // Brighter than base

Organization

Store materials organized by purpose:

code

Assets/Materials/
├── Player/
├── Enemies/
├── Environment/
├── Effects/
└── UI/

Visual Language

Establish consistent meaning:

•Player: Cool colors (blue, cyan)
•Enemies: Warm/danger colors (red, orange)
•Collectibles: Reward colors (gold, green)
•Hazards: Warning colors (red, orange)
•Environment: Neutral (gray, brown)
•Goals: Positive (green, gold)

Output to User

Don't explain material properties:

•"I made your spaceship cyan and the enemies red so they're easy to tell apart"
•"The coins are golden and slightly glowing"
•"Hazards are marked in red"
