Unity使用导入设置创建Texture2DArray和Texture3D

using System.IO;
using UnityEditor;
using UnityEngine;

public class Texture2DArrayExample
{
    [MenuItem("Example/Create Texture 2D Array")]
    private static void CreateTexture2DArray()
    {
        const int width = 64;
        const int height = 64;
        const int depth = 10;
        const TextureFormat format = TextureFormat.ARGB32;

        var tex2dArr = new Texture2DArray(width, height, depth, format, false)
        {
            filterMode = FilterMode.Bilinear,
            wrapMode = TextureWrapMode.Clamp
        };

        // Create a Texture2DArray while changing the color appropriately for each texture
        for (var i = 0; i < depth; i++)
        {
            var color = Random.ColorHSV();
            var pixels = new Color[width * height];
            for (var j = 0; j < width * height; j++)
            {
                pixels[j] = color;
            }

            tex2dArr.SetPixels(pixels, i);
        }

        tex2dArr.Apply();

        AssetDatabase.CreateAsset(tex2dArr, Path.Combine("Assets", "TestTexture2DArray.asset"));
    }
}
