Unity脚本设置场景环境光，实现白天晚上切换

// 所以代码设置的中，假设ambientMode = AmbientMode.Trilight // Trilight == Triple Light 三重光的意思
// 设置为一个傍晚的样子
RenderSetting.ambientMode = AmbientMode.Trilight;
RenderSetting.ambientSkyColor = Color.gray;
RenderSetting.ambientEquatorColor = Color.black;
RenderSetting.ambientGroundColor = Color.black;

或者自定义颜色

RenderSetting.ambientMode = AmbientMode.Trilight;
RenderSettings.ambientSkyColor = new Color(230/255f, 240/255f, 255/255f, 1/255f);
RenderSettings.ambientEquatorColor = new Color(190/255f, 190/255f, 190/255f, 1/255f);
RenderSettings.ambientGroundColor = new Color(229/255f, 229/255f, 229/255f, 1/255f);
