原因如下：

Flickering lighting is usually caused by the Global Illumination Effect when the sun and/or other objects are animated.

闪烁照明通常是由 太阳和/或其他物体动画时的全局照明效果引起的。

The Global Illumination Effect in Lumion analyses surfaces that are lit up by the sun or by artificial light sources. The Effect then places probe lights that emit light in all directions near the lit surfaces to simulate reflected light. These probe lights are reshuffled when the sun and other objects move in a video.

1.1: To prevent the lighting from flickering in a Clip that uses the Global Illumination Effect, you need to render the Clip in 4 Star Output quality. In addition, everything has to remain static, i.e. no moving sun, no animations, and the Wind Effect should be set to a low value so that trees do not sway too much in the wind.

Lumion中的全局照明效果分析被太阳或人造光源照亮的表面。然后，效果将向各个方向发光的探针灯放置在 照明表面附近，以模拟反射光。 当太阳和其他物体在视频中移动时，这些探头灯会重新洗牌。1.1：要防止使用全局照明效果的剪辑中的照明闪烁，您需要 以 4 星输出质量渲染剪辑。此外，一切都必须保持静止，即没有移动的太阳，没有动画，风效果应该设置为较低的值，这样树木就不会在风中摇曳太多。
