上图就是一低模风格的地图模型截图，看上去也很不错对吧
那么怎样把一个模型转化为低模风格的呢？
主要是把顶点数减少，同时将顶点的贴图坐标也做相应改变，可参考以下代码
using UnityEngine;
using System.Collections;
using UnityEditor;
public class FlatShading : MonoBehaviour
{
private Mesh mesh;
void Start()
{
var meshFilters = GetComponentsInChildren<MeshFilter>();
string name = this.gameObject.name;
AssetDatabase.CreateFolder("Assets", name);
foreach (var meshFilter in meshFilters)
{
mesh = meshFilter.mesh;
Vector3[] oldVerts = mesh.vertices;
Vector2[] oldUv = mesh.uv;
int[] triangles = mesh.triangles;
Vector3[] verts = new Vector3[triangles.Length];
Vector2[] uv = new Vector2[triangles.Length];
for (int i = 0; i < triangles.Length; i++)
{
verts[i] = oldVerts[triangles[i]];
uv[i] = oldUv[triangles[i]];
triangles[i] = i;
}
mesh.vertices = verts;
mesh.triangles = triangles;
mesh.uv = uv;
mesh.RecalculateBounds();
mesh.RecalculateNormals();
//save file
string assetName = "Assets/" + name + "/" + mesh.name + ".asset";
AssetDatabase.CreateAsset(meshFilter.sharedMesh, assetName);
AssetDatabase.SaveAssets();
}
string prefabName = "Assets/" + name + ".prefab";
PrefabUtility.CreatePrefab(prefabName, this.gameObject);
AssetDatabase.SaveAssets();
}
}
这段代码可以生成一个新的低模风格的预设，并保存在根目录
