  • Cloud lighting and shading improvements, including: application of atmosphere transmittance to cloud lighting, unification of ambient light calculation for raymarched, baked, and scaled clouds, recalculation of average position for clouds to accomodate density, updating scattering to use average/weighted position estimated from density samples, moving some code into functions, and separating cloud shadows out of scaled cloud shader and into a new shader that renders below the atmosphere

  • :1437623226_rocket_1f680(3): Fixed: fairings fly towards celestial bodies after being jettisoned [Original Bug Report]
  • Fixed: vessel stage deploys after the Go button is pressed while time warp is above 1x and then dropped down to 1x
  • :1437623226_rocket_1f680(3): Fixed: vessel focus behavior is wrong when using stack separators [Original Bug Report]
  • :1437623226_rocket_1f680(3): Fixed: kerbals in non-launch assemblies are lost when launching the vessel [Original Bug Report]
  • Fixed: LY-99 XL gear sometimes hover above runway upon landing
  • Fixed: celestial body trajectories are a solid color when viewed in the Map or Tracking Station
  • Fixed: light tree shows all green lights earlier than intended on maneuver burn timer
  • Fixed: decoupled stage without probe core/pod is controllable

FX and Audio

  • Adjusted Logitech Lighting FX when vehicle crashes
  • Adjusted Logitech Lighting colors when reaching some celestial bodies
  • Fixed: wingtip vortices jump when entering celestial frame of reference

Known Issues

Gridfins GRFN-125 and GRFN-250 are not affected by SAS

  • This is due to a problem with control surfaces and how they interact with SAS that was recently identified. SAS is intended to work with Gridfins in the future, but for now they are manual control only.

PF-AD-XL 2500 Fueled Adapter is invisible when viewed in VAB and Flight

  • Aware of issue, investigating

First Time User Experience Prompt does not appear when vessel loses power for the first time in Flight

  • New to v0.1.5.0, investigating
