Description

KSP 1.8.0 + MH + BG

Video and screenshot shows the problem...sort of,
Sometimes its really obvious, sometimes not. the video quality isn't high enough to show that it seems to surround the kerbal.

settings.cfg is to show the line for 'Line Issue.sfs'

Work Around: Turn off AA

Can confirm that I've been seeing this too. It's more or less visible depending on lighting conditions, camera tilt, zoom level etc. It's difficult to properly capture in a still screenshot, since it's only a single pixel wide and constantly flickering. Looks almost like a scratch on your monitor until you rotate the camera. Seems to show up best on Duna and Eve. It's not seams / gaps in the terrain geometry, although it does loosely follow the curve of the terrain. And it doesn't seem particularly affected one way or the other by anti-aliasing settings. If I had to guess at a cause, I'd say the line is an artifact of the terrain's texture transitioning uncleanly between two different detail levels at a certain distance to the camera. Maybe not even the diffuse texture; it could be the normal map or anything else in the shader really. Oh yeah, and Win10, GTX1050TI, latest drivers yadda yadda. Attaching screenshots.

I've checked this in the latest 1.9 + MH + BG build and can not see the line surrounding the kerbal. Could you please retest this to see if this is still happening.
Thanks

#9 Updated by Anth12 almost 4 years ago

I Tested again with 1.8.0 and then 1.9.1 (added Duna to my testing)

Note: This bug report was for reporting a white thin line around the Kerbal which was obvious in shadow.

Robert Keech: The line I specified in 1.8.0 is now gone in 1.9.1.

(not sure what to set this bug report to...moot?)
