The aerial perspective method described earlier only makes precision issues worse by taking the difference between 2 samples, especially on high variance areas (typically around the horizon) where any imprecisions are amplified. Recall that we are using look-up tables, these are loaded on the graphics card as textures, and they have limited resolution and precision (bit depth). Hmm that looks really strange around the horizon, so what's happening here? Putting It In-GameSo now that we know the method to render aerial perspective, we can plug it in-game, and see what we get. We also must apply transmittance to the observer to second sample (in red on the diagram) for everything to be correct. However, since the look-up tables allow us to get the colour of the sky from any viewpoint, we can re-express the scattered light up to a point/object as the difference between two samples to the edge of the atmosphere, starting from different positions. This is because the look-up tables would otherwise become impractically big and would eat up our memory budget. The look-up tables only allow us to get the light scattered towards us from the edge of the atmosphere, and assume we are always looking towards the edge of the atmosphere, so we cannot use it to directly to get the colour of the atmosphere up to an object. It is supposed to be released for both Xbox and PlayStation platforms at some point after it exits its current Early Access time period.How Aerial Perspective is RenderedThe look-up tables I’ve described earlier can be used to find the colour of the sky for any given viewpoint inside or outside the atmosphere, as well as how much the atmosphere occludes celestial objects behind it (this is known as transmittance or also extinction, it describes how much of the original object’s light is transmitted and makes it to the observer). Right now, the game is currently available on the PC via Steam and the Epic Games Store for $49.99. The new game has promised to offer players a number of new features, including setting up planetary colonies and offering access to interstellar travel. The game itself is a sequel to the popular indie-developed space sim. Since the game has been in Early Access starting in February, it's strange that this issue hasn't popped up beforehand nor has a fix been released yet. I'll share more details on a timeline when I have one. It's currently being tested and we're aiming for a hotfix since we see this as critical. The team is aware of this issue and we have a fix. The post on the game's official message board states: However, if you don't feel comfortable editing the registry, the good news is that the game's developer Intercept Games is working on a hotfix to deal with this problem.
