With this post process Material, you can add the atmosphere to an existing planet, which will look quite realistic, whether viewing from the planet surface or outer space. By adjusting the Scale parameter, the atmosphere can be added to planets of different sizes.
The Material best interacts with rough surfaces adding sky light and light attenuation to them (reddish mountain peaks at sunsets). Regular shapes with high gloss polished surfaces may look unnatural in the day time because they will receive reflections of the sky only via the Screen Space Reflections (although it can render a nice looking ocean surface). Currently the atmosphere receives no shadows from any objects except its own planet.
For correct rendering of the brightness of the atmosphere, Pre-Exposure should be disabled in the project settings.
Planetary Atmosphere Material utilizes certain averaging and simplification techniques to compute Rayleigh and Mie scattering, which require no precomputation but can give a realistic look of an atmosphere with reasonable performance impact. Please try the demo first to make sure this Material meets your performance requirements.
使用此后期处理材料，您可以将大气添加到现有行星中，无论是从行星表面还是外太空观察，这些行星看起来都非常逼真。 通过调整尺度参数，可以将大气添加到不同大小的行星中。
这种材料与粗糙表面的相互作用最好，为它们添加了天空光和光衰减（日落时的红色山峰）。 具有高光泽抛光表面的常规形状在白天可能看起来不自然，因为它们只能通过 屏幕空间反射 （虽然它可以渲染一个漂亮的海洋表面）。 目前，除了它自己的星球之外，大气没有任何物体的阴影。
为了正确渲染大气的亮度, 预曝光 应在项目设置中禁用。
行星大气材料利用一定的平均和简化技术来计算瑞利和Mie散射，这不需要预先计算，但可以给出一个具有合理性能影响的大气的现实外观。 请先尝试演示，以确保此材料符合您的性能要求。
