核心原则

Godot 资源文件是纯文本，AI 可以直接通过 write_to_file 创建材质、形状、环境等资源。

---

一、文件结构

[gd_resource type="ResourceType" format=3 uid="uid://xxx"]

[resource]
property1 = value1
property2 = value2

---

二、材质资源 (StandardMaterial3D)

2.1 基础材质

[gd_resource type="StandardMaterial3D" format=3]

[resource]
albedo_color = Color(0.8, 0.2, 0.2, 1)
roughness = 0.8
metallic = 0.0

2.2 金属材质

[gd_resource type="StandardMaterial3D" format=3]

[resource]
albedo_color = Color(0.9, 0.9, 0.9, 1)
roughness = 0.3
metallic = 0.9
metallic_specular = 0.5

2.3 发光材质

[gd_resource type="StandardMaterial3D" format=3]

[resource]
albedo_color = Color(1, 0.8, 0, 1)
emission_enabled = true
emission = Color(1, 0.8, 0, 1)
emission_energy_multiplier = 3.0

2.4 透明材质

[gd_resource type="StandardMaterial3D" format=3]

[resource]
transparency = 1
albedo_color = Color(0.2, 0.5, 1, 0.5)

2.5 无光照材质

[gd_resource type="StandardMaterial3D" format=3]

[resource]
shading_mode = 0
albedo_color = Color(1, 1, 1, 1)

2.6 带纹理材质

[gd_resource type="StandardMaterial3D" load_steps=2 format=3]

[ext_resource type="Texture2D" path="res://textures/brick.png" id="1_albedo"]

[resource]
albedo_texture = ExtResource("1_albedo")
roughness = 0.9

---

三、常用材质属性参考

属性	类型	说明

albedo_texture	Texture2D	颜色贴图
roughness	float (0-1)	粗糙度，0=光滑，1=粗糙
metallic	float (0-1)	金属度
metallic_specular	float (0-1)	金属高光
emission_enabled	bool	启用发光
emission	Color	发光颜色
emission_energy_multiplier	float	发光强度倍数
transparency	int	0=不透明, 1=Alpha, 2=预乘Alpha
cull_mode	int	0=背面剔除, 1=正面剔除, 2=不剔除
shading_mode	int	0=无光照, 1=逐顶点, 2=逐像素(默认)
normal_enabled	bool	启用法线贴图
normal_texture	Texture2D	法线贴图
normal_scale	float	法线强度
