| nameID | 属性名称 ID，使用 Shader.PropertyToID 获取。 |
| name | 属性名称，例如“_Color”。 |
| value | 要设置的颜色值。 |
设置指定的颜色值。
许多着色器使用多种颜色。使用 SetColor 可更改颜色（由着色器属性名称或唯一的属性名称 ID 标识）。
When setting color values on materials using the Standard Shader, you should be aware that you may need to use EnableKeyword to enable features of the shader that were not previously in use. For more detail, read Accessing Materials via Script.
Common color names used by Unity's builtin shaders:
"_Color" is the main color of a material. This can also be accessed via color property.
"_EmissionColor" is the emissive color of a material.
