New features, options and improvements

• AI & New Behavior:
  • A general issue with AI that has been around for a while affecting things has been fixed;
  • Straighten AI's trajectory when starting reworked properly;
  • Prevent AIs from redlining before the start improved as well;
  • Adjust shifting for slow sectors should be working now;
  • physics.setAISplineAbsoluteOffset() should work a bit better;
  • Cooldown lap shouldn’t cause cars to keep teleporting around in the end;
  • AI in headless mode going backwards fixed;
• Glass materials losing normal maps are fixed;
• Bots online mistakenly shown on the map are fixed (recent regression), hidden cars no longer show up in overlay leaderboard or in the new menu;
• The issue with CSP not launching on Linux fixed;
• Simulation occasionally getting deadlocked with car teleports fixed;
• Smart Shadows:
  • Adaptive first split rewritten, no longer applies to drivable and cockpit cameras;
  • Option for adaptive first split is visible again;
  • Distant cascade updated to respect tree textures again;
• Surface noise upgrade fixed, scale adjusted (even previous Perlin was a bit too high, and newly added simplex was really wild);
• New KN5 loader sharing materials across cars fixed (previously, the case of basic-and-then-skin-overriden material would misbehave);
• Shaders clamp output color to make sure it’s never negative, so even wildly misconfigured materials won’t break rendering too much;
• nePBR shaders can handle clear coat F0 above 100% a bit better (F0 should never exceed 100%);
• Shaders better handle extColoredReflection above 100%;
• A few improvements to the shape and shading of fallback LOD;
• Default Weather FX: some small adjustments for grass shading and fog hues, new Volumetric fog effect (experimental, disabled by default);
• CSP Debug:
  • Positioning of teleport preview improved;
  • Holding Ctrl to teleport a car no longer creates a force if the click was on the car;
  • Toggle extra car animations;
  • Shortcuts for extra observe commands;
  • A helper to quickly switch between car LODs;
• Increase conditions limits tweak is enabled by default, allowing setting road temperature above 36° C;
• Incorrect (zeroed) normals in KN5 are corrected during loading, fixing some visual artifacts (in particular, with Windscreen FX reflections);
• Neck FX: Maximum offset now allows to configure values per-axis;
• Piece particles:
  • Motion parameters updated to increase visual variety;
  • Particles aren’t sliding around on a flat surface anymore;
  • Largeness of rare lucky particles reduced;
• Rain drops flying off wheels and arches improved a bit;
• Photo app: layout of lens tab is a bit tidier;
• Splitscreen:
  • Stability control and other AI tweaks no longer apply to the second car;
  • System shortcuts changing ABS, TC and such apply to both cars at once;
  • Input smoothing for second car is disabled;
  • Grass FX is properly shown in the second view;
  • Second view also got its own reflection cubemap;
  • Discrepancy in headlights intensity fixed;
• OBS views:
  • New Higher quality option with dedicated grass spawn and shadows set;
• ac.GeometryShot:update() got an overload accepting actual view and projection matrices, as well as options for dedicated grass spawn and shadow maps;
• Geometry shots: grass is drawn before particles;
• If HDR is enabled, but not available, config loaded with ac.INIConfig.cspModule(ac.CSPModuleID.DXGITweaks) will have that option disabled;
• Crashes name format updated to be a bit shorter, but include CSP version as well;
• Ash motion fixed;
• In-game license plate generator updated to better handle a case with textures taking a while to load;
• INIpp:
  • Use @DISCARD=1 in both templates/mixins/generators or regular sections to discard them entirely (better alternative to ACTIVE=0);
  • Add @PARENT=SECTION_NAME to copy values not present in this section from SECTION_NAME, list several to keep copying missing values;
  • Use discard() in @OUTPUT to discard the final section (useful for templates doing nothing but spawning generators);
  • A couple of smaller fixes and optimizations (the parser is about 60% faster);
• Detection range for ac.getCarBlindSpot() and BLIND_SPOT input increased from 20 to 200 m;
• ac.getSetupValue() returns actual nil if value is missing, caches results across the calls, docs got a hint on how to deal with GEAR_SET;
• New ac.forceDetailedCarLOD() for Gameplay API, some of default OBS views use it to force detailed LOD;
• ui.progressBar() fixed;
• New fields for ac.CarPhysicsValueID for altering parameters of automatic shifter live;
• New ac.getSceneShadow() for Weather FX styles sampling shadow map in camera position (using fourth cascade);
• New getApproximateSceneShadow(position) for scene shaders (uses fourth cascade as well);
• Use [HEADER] PARSER=INIPP in car data to use INIpp features, including includes, or read('data/car.ini/SECTION/KEY', 0) to access other files;
• Car non-physics scripts (but not scriptable displays) load in headless mode (apparently, there are some cool mods out there that use those for physics-related stuff, which is something I didn’t anticipate at all);
• CSP loads GUIDs.txt even if it’s a read-only file;
• A few small fixes for render stats app;
