public static int pixelLightCount ;

説明

オブジェクトに影響を与える、ピクセルライトの最大数を設定する。

If there are more lights illuminating an object, the dimmest ones will be rendered as vertex lights.

Use this from scripting if you want to have finer control than offered by quality settings levels.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Example() { QualitySettings.pixelLightCount = 1; } }
