Unity Material

besty0728/unity-material

Edit Unity material and shader properties across Built-in/URP/HDRP — colors, textures, floats, keywords, render queue, batch-apply. Use when changing how a surface looks, tweaking material parameters, or swapping shaders. 编辑材质与 Shader 属性(Built-in/URP/HDRP:颜色、贴图、浮点值、关键字、渲染队列、批量应用);当用户要调整物体外观、改材质参数或切换 Shader 时使用。

Unity Material Skills

> BATCH-FIRST: Use *_batch skills when operating on 2+ objects/materials.

Operating Mode

Approval (default): all mutating skills (material_create, material_create_batch, material_assign, material_assign_batch, material_duplicate, material_set_color / _emission / _texture / _float / _int / _vector / _keyword / _render_queue / _shader / _texture_offset / _texture_scale / _gi_flags, and the *_batch variants) need user grant; grant triggers a single server-side execution that returns the result.
Auto / Bypass: those skills execute directly.
Query skills (material_get_properties, material_get_keywords) are SkillMode.SemiAuto — they run in all three modes without grant.
This module contains no Delete / PlayMode / Reload / high-risk skills (no NeverInSemi); to delete a material asset, call the asset module.

Guardrails

DO NOT (common hallucinations):

material_set_metallic / material_set_smoothness do not exist → use material_set_float with propertyName="_Metallic" or "_Glossiness" (Standard) / "_Smoothness" (URP)
material_set_color r/g/b/a range is 0–1, not 0–255
material_set_property does not exist → use the specific setter: material_set_float, material_set_int, material_set_vector, material_set_color
material_get_color does not exist → use material_get_properties (returns all properties including colors)

Routing:

For shader changes → material_set_shader (this module)
For texture tiling → material_set_texture_scale / material_set_texture_offset
Pipeline-specific property names differ: check Render Pipeline Compatibility table in this doc

> Object Targeting: Most single-object skills accept name (GameObject name) or path. Behaviour of path:

> - In material_set_* / material_get_* (color/emission/texture/float/int/vector/keyword/shader/render_queue/gi_flags/properties), path may be either a GameObject hierarchy path *or* a material asset path like Assets/Materials/X.mat — the skill auto-detects (paths starting with Assets/ or ending with .mat are treated as material assets).

> - In material_assign, path is a GameObject hierarchy path only; the material to assign goes in the separate materialPath parameter.

Render Pipeline Compatibility

Skills auto-detect and adapt to your render pipeline:

|----------|---------------|----------------|------------------|

Best Practices

Save materials as assets for reuse
Use material instances (by name) for runtime changes
Use material assets (by path) for persistent changes
Check shader property names in Unity Inspector
URP/HDRP have different property names than Standard

Exact Signatures

Exact names, parameters, defaults, and returns are defined by GET /skills/schema or unity_skills.get_skill_schema(), not by this file.

How to use it

Copy the folder

Take besty0728/unity-material from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
