The screen shots are one patch out of date but will post anyway (it was a low priority issue). Bug still in effect because I was just in the game to check the device names for this post and saw some beams shining through (v1.4.2 3266). Apologies if already reported; I searched but didn't find a related bug report. Build: v.1.4.1 3261 & 3262; v1.4.2 3266 Mode: Survival Mode: Singleplayer Seed-ID: 43351 Reproducibility: 100% if it's sunny with sun at right angle to shine through the device to cast a shadow that can be seen from the character's POV. Severity: Trivial (immersion-breaking) Type: Global Summary/Description: Sun shines through certain solid devices. Objects affected: CV Thruster S, CV Thruster Enclosed M, CV Thruster Regular L, CV Pulse Laser Turret (retractable). Patch of light and shadow of the Shutter Window L grate that was installed on the exhaust (exterior) end of a Thruster S. Exterior view of same thruster (exhaust end). Bank of Enclosed M thrusters. Regular L thruster. Pulse Laser Turret (retractable). Character is standing in an enclosed area that really should be pitch-black even in daylight (but isn't).
