有时候材质做完后需要更改贴图,或者增加贴图,数量少的时候可以一张张添加和修改,数量多的时候就只能代码生成了。原理是通过名字的关联:主贴图和法线贴图大多数只是后缀的不同上,如果不是那是美术规范没做好啊,代码很简单,基本是编辑器类的代码。
这个是还没完善的特定版代码,如直接使用需要更改文件夹名字和贴图后缀。

public class Transferandmapnormal : EditorWindow
{

static void AutoAddNormalinmaterials()
{ Rect wr = new Rect(, , , );
Transferandmapnormal window = (Transferandmapnormal)EditorWindow.GetWindowWithRect(typeof(Transferandmapnormal), wr, true, "AutoAddNormal");
window.Show();
} public List<Material> scensmaterial = new List<Material>();

void OnGUI()

if (selection.Length == ) return; foreach (Material test in selection)

TextureImporter texture = (TextureImporter)AssetImporter.GetAtPath("Assets/Resources" + "/" + sourceTexturespath[i]);
Debug.Log("Assets/Resources" + "/" + sourceTexturespath[i]);
if (texture != null)
{
texture.textureType = TextureImporterType.Bump;
AssetDatabase.ImportAsset("Assets/Resources" + "/" + sourceTexturespath[i]);
string correctString=sourceTexturespath[i].Replace(".jpg","");
Debug.Log(correctString);
Texture TempTexture =Resources.Load(correctString) as Texture;
scensmaterial[i].SetTexture("_BumpMap", TempTexture);
}
}
}
AssetDatabase.Refresh(); }
public void testpath()
{
Object[] selection = (Object[])Selection.objects;
//合法性处理
if (selection.Length == ) return;
//批量导入贴图
foreach (Object obj in selection)
{
//取得每一张贴图
Texture texture = (Texture)obj;
//获得贴图路径
string localpath = AssetDatabase.GetAssetPath(texture);
Debug.Log(localpath);
TextureImporter importer = (TextureImporter)AssetImporter.GetAtPath(localpath);
//设置贴图类型
importer.textureType = TextureImporterType.Bump;
//导入项目资源
AssetDatabase.ImportAsset(localpath);
}
AssetDatabase.Refresh(); } }
api解析:
[ExecuteInEditMode]//在编辑器模式下可调用
[MenuItem("Window/AutoAddNormal")]//在window工具栏下增AutoAddNormal选项
window.Show();//展示新的窗口
GUILayout.Button("应用法线贴图到材质",
GUILayout.Width(200))//添加按钮
Object[] selection = Selection.GetFiltered(typeof(Material),
SelectionMode.Editable | SelectionMode.TopLevel);//把选取的物体过滤掉非Material类型的object到object选项。
TextureImporter –textureimporeter类可以调各种图片输入器的参数,包括图片的类型也是在这里调节。
AssetDatabase.ImportAsset(localpath);//重新载入asset资源
importer.textureType = TextureImporterType.Bump;//将图片的类型改为法线
AssetDatabase.Refresh();//刷新资源
使用方法:
1.在project选取材质
2.点击按键2,批量获取材质和贴图路径
3.获取法线贴图路径并且贴在材质球上
注意事项:(1.法线贴图要放在Resources文件夹上, 2.这个脚本需要修改再使用,因为我还没做通用版本,有些是我自己的文件路径,所以使用需要修改
private string textureSuffix = "_NRM.jpg";
private string docPath = "DWSJ.fbm";这两句,替换到你自己的贴图后缀和文件名字。
