unity3d - Unity LoadAssetBundles 将 Material 更改为 Pink ？(URP)

Question

在 Unity URP 中，当我从服务器加载 Assetbundle 时，它​​的所有材质着色器都是正确的，但对象变为 PINK。任何想法如何解决这个问题？

Answer 1

材料可能仅在编辑器中显示为粉红色。它应该在构建中正常工作。

但是，在游戏屏幕上到处看到粉红色会很烦人。您可以使用以下脚本在编辑器中修复此问题。

using TMPro;
using UnityEngine;
using UnityEngine.UI;

#if UNITY_EDITOR
    public static class AssetBundleEditorUtil
    {
        public static void FixShadersForEditor(GameObject prefab)
        {
            var renderers = prefab.GetComponentsInChildren<Renderer>(true);
            foreach (var renderer in renderers)
            {
                ReplaceShaderForEditor(renderer.sharedMaterials);
            }

            var tmps = prefab.GetComponentsInChildren<TextMeshProUGUI>(true);
            foreach (var tmp in tmps)
            {
                ReplaceShaderForEditor(tmp.material);
                ReplaceShaderForEditor(tmp.materialForRendering);
            }
            
            var spritesRenderers = prefab.GetComponentsInChildren<SpriteRenderer>(true);
            foreach (var spriteRenderer in spritesRenderers)
            {
                ReplaceShaderForEditor(spriteRenderer.sharedMaterials);
            }

            var images = prefab.GetComponentsInChildren<Image>(true);
            foreach (var image in images)
            {
                ReplaceShaderForEditor(image.material);
            }
            
            var particleSystemRenderers = prefab.GetComponentsInChildren<ParticleSystemRenderer>(true);
            foreach (var particleSystemRenderer in particleSystemRenderers)
            {
                ReplaceShaderForEditor(particleSystemRenderer.sharedMaterials);
            }

            var particles = prefab.GetComponentsInChildren<ParticleSystem>(true);
            foreach (var particle in particles)

                if (renderer != null) ReplaceShaderForEditor(renderer.sharedMaterials);
            }
        }

        public static void ReplaceShaderForEditor(Material[] materials)
        {
            for (int i = 0; i < materials.Length; i++)
            {
                ReplaceShaderForEditor(materials[i]);
            }
        }

        public static void ReplaceShaderForEditor(Material material)
        {
            if (material == null) return;

            var shaderName = material.shader.name;
            var shader = Shader.Find(shaderName);

            if (shader != null) material.shader = shader;
        }
    }
