 通过Texture2D的EncodeToPNG方法将纹理转为图片形式

material.GetTexture方法通过属性名获取纹理贴图

material.SetTexture方法通过属性名设置纹理贴图

属性名可在shader代码中查看

using UnityEngine;
using System.IO;public class TextureSaver : MonoBehaviour
{public Material targetMaterial;public string textureName = "_MainTex"; // 可自定义材质属性名public void SaveMaterialTexture(){if (targetMaterial == null){Debug.LogError("未指定目标材质球！");return;}Texture mainTex = targetMaterial.GetTexture(textureName);if (mainTex == null){Debug.LogError($"材质中未找到纹理属性：{textureName}");return;}if (mainTex is Texture2D){SaveTexture2D(mainTex as Texture2D);}else if (mainTex is RenderTexture){SaveRenderTexture(mainTex as RenderTexture);}else{Debug.LogError("不支持此纹理类型：" + mainTex.GetType());}}void SaveTexture2D(Texture2D texture){if (!texture.isReadable){Debug.LogError("纹理不可读！请在导入设置中启用 Read/Write Enabled");return;}byte[] bytes = texture.EncodeToPNG();string filePath = Path.Combine(Application.persistentDataPath, "SavedTexture.png");File.WriteAllBytes(filePath, bytes);Debug.Log("保存成功：" + filePath);}void SaveRenderTexture(RenderTexture rt){Texture2D tex2D = new Texture2D(rt.width, rt.height, TextureFormat.RGBA32, false);RenderTexture.active = rt;tex2D.ReadPixels(new Rect(0, 0, rt.width, rt.height), 0, 0);tex2D.Apply();RenderTexture.active = null;SaveTexture2D(tex2D);Destroy(tex2D);}
