Unity GameObject贴图资源提取扩展方法

• 获取Material的所有Texture

        public static List GetAllTexture(this Material mat)
        {
            List textures = new List();
            List texNames = new List();
            mat.GetTexturePropertyNames(texNames);
            foreach (var propertyName in texNames)
            {
                //Debug.Log(propertyName);
                Texture tex = mat.GetTexture(propertyName);
                if (tex != null)
                {
                    if (!textures.Contains(tex))
                    {
                        textures.Add(tex);
                    }
                }
            }
            return textures;
        }

• 获取GameObject的所有Material

        public static List GetAllMaterial(this GameObject gameObject)
        {
            SkinnedMeshRenderer[] skinnedMeshes = gameObject.GetComponentsInChildren();
            MeshRenderer[] meshes = gameObject.GetComponentsInChildren();
            List mats = new List();
            foreach (var skin in skinnedMeshes)
            {
                foreach (var mat in skin.sharedMaterials)
                {
                    if (!mats.Contains(mat))
                    {
                        mats.Add(mat);
                    }
                }
            }
            foreach (var mesh in meshes)
            {
                foreach (var mat in mesh.sharedMaterials)
                {
                    if (!mats.Contains(mat))
                    {
                        mats.Add(mat);
                    }
                }
            }
            return mats;
        }

• 获取GameObject的所有Texture

        public static List GetAllTexture(this GameObject gameObject)
        {
            List mats = gameObject.GetAllMaterial();
            List textures = new List();
            foreach (var mat in mats)
            {
                textures.AddRange(mat.GetAllTexture());
            }
            return textures;
        }
