JavaScript => public Cubemap(size: int, format: TextureFormat, mipmap: bool)
C# => public Cubemap(int size, TextureFormat format, bool mipmap);

Parameters 参数

size	Width/height of a cube face in pixels. 立方体面的宽高（像素）。
format	Pixel data format to be used for the Cubemap. 用于该立方体贴图的像素数据格式。
mipmap	Should mipmaps be created? 是否创建多级纹理贴图？

Description 描述

Create a new empty cubemap texture.
新建空立方体贴图纹理。

The texture will be size on each side and can be created with or without mipmaps.
在每边该贴图将会是宽高匹配并且可以创建或不创建多级纹理贴图。

Usually you will want to set the colors of the texture after creating it, using SetPixel and Apply functions.
通常创建贴图后你想设置它的颜色，使用SetPixel和Apply函数。

JavaScript:

var texture: Cubemap;
 
function Start () {
	// Create a new Cubemap texture.
	texture = new Cubemap (128, TextureFormat.ARGB32, false);
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Cubemap texture;
    void Start() {
        texture = new Cubemap(128, TextureFormat.ARGB32, false);
    }
}
