原因如下：

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

閃爍照明通常是由 太陽(yáng)和/或其他物體動(dòng)畫時(shí)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陽(yáng)或人造光源照亮的表面。然后，效果將向各個(gè)方向發(fā)光的探針燈放置在 照明表面附近，以模擬反射光。 當(dāng)太陽(yáng)和其他物體在視頻中移動(dòng)時(shí)，這些探頭燈會(huì)重新洗牌。1.1：要防止使用全局照明效果的剪輯中的照明閃爍，您需要 以 4 星輸出質(zhì)量渲染剪輯。此外，一切都必須保持靜止，即沒有移動(dòng)的太陽(yáng)，沒有動(dòng)畫，風(fēng)效果應(yīng)該設(shè)置為較低的值，這樣樹木就不會(huì)在風(fēng)中搖曳太多。
