Csharp 如何通过脚本将material 渲染模式更改为淡入淡出

material 渲染模式现在默认设置为"不透明".

到目前为止，我做到了:

if (g.GetComponent<SkinnedMeshRenderer>() != null)
                {
                    Material[] mats = g.GetComponent<SkinnedMeshRenderer>().materials;
                }

material 位于索引0处只有一种material ，但我不确定如何访问material 的渲染模式以及如何将其更改为淡入淡出.

到目前为止我所做的try :

我创建了一个新的公共静态类:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public static class MaterialUtils
{
    public enum BlendMode
    {
        Opaque,
        Cutout,
        Fade,
        Transparent
    }

    public static void SetupBlendMode(Material material, BlendMode blendMode)
    {
        switch (blendMode)
        {
            case BlendMode.Transparent:
                material.SetOverrideTag("RenderType", "Transparent");
                material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.SrcAlpha);
                material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);
                material.SetInt("_ZWrite", 0);
                material.DisableKeyword("_ALPHATEST_ON");
                material.EnableKeyword("_ALPHABLEND_ON");
                material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
                material.renderQueue = (int)UnityEngine.Rendering.RenderQueue.Transparent;
                material.SetFloat("_Mode", 3.0f);
                break;
            case BlendMode.Opaque:
                material.SetOverrideTag("RenderType", "");
                material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.One);
                material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.Zero);
                material.SetInt("_ZWrite", 1);
                material.DisableKeyword("_ALPHATEST_ON");
                material.DisableKeyword("_ALPHABLEND_ON");
                material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
                material.renderQueue = -1;
                material.SetFloat("_Mode", 0.0f);
                break;
            default:
                Debug.LogWarning("Warning: BlendMode: " + blendMode + " is not yet implemented!");
                break;
        }
    }
}

然后返回编辑器脚本:

Inside OnGUI :

if (GUILayout.Button("Start"))
        {
            allChildren = new List<Transform>();

            foreach (Transform g in transform.GetComponentsInChildren<Transform>())
            {
                var level = ObjectLevel(g);
                names.Add(" Level " + level.ToString());

                if (g.GetComponent<SkinnedMeshRenderer>() != null)
                {
                    Material[] mats = g.GetComponent<SkinnedMeshRenderer>().sharedMaterials;
                    Material mat = mats[0];
                    MaterialUtils.SetupBlendMode(mat, isOpaque ? MaterialUtils.BlendMode.Fade : MaterialUtils.BlendMode.Fade);
                    mats[0] = mat;
                    allChildren.Add(g);
                }
            }
        }

但我在编辑中得到警告:

警告:BlendMode:尚未实现淡入淡出！

在线:

MaterialUtils.SetupBlendMode(mat, isOpaque ? MaterialUtils.BlendMode.Fade : MaterialUtils.BlendMode.Opaque);

渲染模式仍然不透明.
