Arctic Aurora Landscape 适配UE4.24 - 4.27, 5.0 - 5.1北极山区环境
This arctic mountain environment has a highly realistic landscape featuring several types of Aurora Borealis level. Landscape terrain using detailed shaders and a variety of assets covering the mountain. Ranging from high level trees both snowed in and dead branches to small sapling trees with clusters of snow chunks and deposits of snow. A variety of mountain ranges are scattered across to add depth and life to the scene. A background layer of mountain allows the viewer to feel the distance and overall scale of the time. On top of that realistic particles featuring rolling snow clouds over the mountain peaks and shooting stars, you can really the authenticity of the scene.
Note: The scenes use physically accurate lighting values which is why the sun intensity makes it so overblown. You need use or add a cinecamera and tweak the ISO and shutter speed values. You also need to ensure you have enabled ue4 extend default luminance range in the project settings.

这个北极山区环境拥有高度逼真的景观，具有多种类型的极光级别。景观地形使用了详细的着色器和覆盖山体的各种资产。从积雪和枯枝的高层树木，到带有雪块和积雪的小树苗。各种山脉错落有致，为场景增添了深度和活力。山峰背景层让观众感受到时间的距离和整体规模。再加上山峰上滚动的雪云和流星等逼真的颗粒，让人真切感受到场景的真实性。
注意：场景使用了物理上精确的照明值，这就是为什么太阳强度会如此夸张的原因。您需要使用或添加电影摄影机，并调整 ISO 和快门速度值。您还需要确保在项目设置中启用了 ue4 扩展默认亮度范围。
