Tracks – Surface tweaks - ac-custom-shaders-patch/acc-extension-config GitHub Wiki

Along with regular surface properties, such as FRICTION or DAMPING, there are now some extra ones added by CSP.

• _EXT_SURFACE_TYPE: type of the surface (overrides guessing based on WAV).
  • EXTRATURF;
  • GRASS;
  • GRAVEL;
  • KERB;
  • OLD;
  • SAND.
• _EXT_SURFACE_TYPE_MODIFIER: adjusts SurfacesFX behavior for sand, grass and gravel. Default value is REGULAR.
  • LOOSE;
  • REGULAR;
  • FIRM.
• _EXT_PERLIN_NOISE: set to 0 to make sure sine noise will be used despite CSP settings, or to 1 to replace sine noise with perlin noise (SIN_HEIGHT and SIN_LENGTH would still be used, but now for perlin instead).
• _EXT_PERLIN_OCTAVES: number of octaves for perlin noise, from 1 to 10.
• _EXT_PERLIN_PERSISTENCE: perlin noise persistence (amplitude multiplier for following octaves).

Note: if surface type is not set explicitly, SurfacesFX will activate for surfaces with DIRT_ADDITIVE ≥ 0.7, or surfaces with DIRT_ADDITIVE ≥ 0.3 and (FRICTION < 0.9 or WAV set to “grass.wav”, “gravel.wav” or “sand.wav”).
