public Vector2[] uv3 ;

説明

存在する場合、メッシュの 3 番目のテクスチャ座標設定

// Generate planar uv coordinates for the third uv set

using UnityEngine;

public class ExampleClass : MonoBehaviour { void Start() { Mesh mesh = GetComponent<MeshFilter>().mesh; Vector3[] vertices = mesh.vertices; Vector2[] uvs = new Vector2[vertices.Length];

for (int i = 0; i < uvs.Length; i++) uvs[i] = new Vector2(vertices[i].x, vertices[i].z);

mesh.uv3 = uvs; } }
