Coding Adventure: Atmosphere

Sebastian Lague explains how he implemented realistic atmospheric scattering and planetary atmospheres in Unity.

The planets in my solar system project are looking a bit hostile and uninviting, so in this video I'll be attempting to add some cozy atmospheres around them. Watch the previous solar system video: here: youtu.be/lctXaT9pxA0 Some notes: • I made a little build where you can play with the atmosphere settings yourself, which you can find over here if you're interested: sebastian.itch.io/atmosphere-experiment • A number of knowledgeable people have pointed out in the comments that reality is not nearly as simple as my little diagram around the 4 and a half minute mark, and that light does not literally wiggle up and down like a wave, so please note that the diagram is incorrect! • This project was inspired by the game Outer Wilds, which I highly recommend playing!
