為什么Lumion渲染三維動(dòng)畫(huà)視頻比圖片的亮度更低?
Why are Movies sometimes darker than Photos? 為什么“電影”有時(shí)比“照片”更暗?
1. Here's why. 原因如下
If you are using the Hyperlight Effect, please note that Hyperlight is rendered with a shorter range for bouncing light rays in Movies and Image Sequences than on Photos.
如果您使用的是超光效果,請注意,超光在影片和圖像序列中反射光線(xiàn) 的范圍比在照片中更短。
For that reason, Hyperlight in Movies and Image Sequences will appear darker compared to Photos.
因此,與“照片”相比,影片和圖像序列中超光將顯示得更暗。
This is by design in order to keep render speeds high and noise low in Movies and Image Sequences.
這是設計使然,以便在影片和圖像序列中保持高渲染速度和低噪點(diǎn)。
Example of high range Hyperlight on a Photo rendered via the Current shot tab in Movie Mode:
在影片模式下通過(guò)“當前拍攝”選項卡 渲染的照片上的高范圍超光示例:
Example of low range Hyperlight on a Photo rendered via the Image sequence tab in Movie Mode:
在影片模式下通過(guò)“圖像序列”選項卡渲染的照片上的低范圍超光示例:
2. Workarounds2. 解決方法
2.1: Consider adding the Global Illumination Effect to your Clip.
2.1:考慮將全局照明效果添加到剪輯中。
Please follow the advice in the article below in order to avoid flickering lighting:
請遵循以下文章中的建議,以避免閃爍的照明:
- Knowledge Base: 為什么Lumion渲染有些視頻的燈光會(huì )閃爍?
Example of low range Hyperlight on a Photo rendered with a Global Illumination Effect via the Image sequence tab in Movie Mode:
在影片模式下通過(guò)“圖像序列”選項卡使用全局照明效果渲染的照片上的低范圍超光示例:
2.2: An alternative to the Global Illumination Effect would be to add Omni Lights, or Area Lights facing upwards, to simulate additional bouncing light rays.
2.2:全局照明效果的替代方法是 添加泛光源或朝上的區域光源,以模擬額外的反射光線(xiàn)。
Example of low range Hyperlight on a Photo rendered with an Area Light facing the ceiling via the Image sequence tab in Movie Mode:
在短片模式下通過(guò)“圖像序列”選項卡渲染區域光源朝向天花板的照片上的低范圍超光示例:
