Terminator of thin atmospheres is incorrectly shaded at a distance

[Brimfyr]

Game Version​

2026.7.3.4826

Operating System​

Windows 11

What Happened​

The area at the terminator of thin atmospheres (e.g. Mars) is not correctly shaded at a distance, but when you get close to it the proper shading becomes visible. The same effect seems to be non-existent or negligible with atmospheres like Earth's.

What Was Expected​

The atmosphere is correctly shaded at all distances.

Reproduction Steps​

1. Universe > Bodies > Sol > Mars (2) > Mars to view Mars
2. Shift + C to switch to free cam
3. # to open the command window and set camspeed to something higher like 1000000 m/s (camspeed 1000000 ms)
4. Position the camera above the terminator and make note of how abrupt the shading is, not how you'd expect it to look
5. Move closer to the planet with the arrow keys until you notice the shading switch to what appears to be the correct form
6. Move back and forth along this threshold to see how it switches

Reproduction Rate​

Always.
