Sol Weather Engine For Assetto Corsa 1.5.4 & 1.6 – Released

Peter Boese has released new versions of the amazing Sol Weather Engine add-on for Assetto Corsa.

The new version also adds new dramatic lightning & thunder effects, including sounds.

Sol 1.5.4 Changelog

  • core: added support to switch Sol version in weatherFX

Sol 1.6 Changelog

  • apps: sol_weather 9.92 – apps: sol_config 0.87 # Both apps are now able to recognize a weather implementation switch. # Its now possible to switch between different Sol versions ingame, if # those Sol versions are prepared as different CSP weather implementations.
  • core: added error handling for incompatible Assetto Corsa installs – core: replaced all lua color conversions and mixing with weatherFX functions – core: added support to switch Sol version in weatherFX – core: working LUTs based on sunangles -90°..90°
  • core: directional ambient light: # 2 switches in sol_config/page 8 for 3 function modes: # ambient__use_directional_ambient_light and ambient__use_overcast_sky_ambient_light are activated, will make a combination of the old directional ambient light from Sol 1.5.1 controlled by the overcast modifier # only ambient__use_directional_ambient_light is activated – this is just the Sol 1.5.1 directional ambient light # only ambient__use_overcast_sky_ambient_light is activated – directional ambient light is just calculated by the view angle and the color of the sky – core: directional ambient light is calculated every frame (no stutter with “use cpu split”)
  • sky: new skysim class and new cloud classes # The clouds are managed with layers for different cloud types # Clouds are repositioned like a conveyor belt. # They are positioned in a simple grid. This will be change in future releases.
  • sky: 2 types of performance improvements with sol_config/page 6 # 0 = the color calculation of all clouds are done every frame # 1 = only the clouds in FOV are calculated every frame, the others are calculated per “clouds__render_per_frame” # 2 = the amount of clouds, which are calculated per frame is strictly “clouds__render_per_frame”
  • sky: new clouds lightbounce calculation for better simulation of ambient light and night illumination – sky: added lightning (first rough implementation (single slow flash to prevent epilepsy)
  • sky/lightning: added support for “feature request” # feature requests will come in further CSP version # lightnings will be triggered, if feature is requested in photo mode

  • config: added ppfilter saturation parameter – config: added new page “sound” (page 10) – config: clouds__render_limiter = 2 by default # if you use very high time progressions, set it to 1
  • ppfilter/custom configs: removed __Sol_ACC and __Sol_HC
  • folders: removed the spaces from content/weather/ folders, to prevent problems with online usage
