Surface Particle Manager

SurfaceParticleManager inspector.

SurfaceParticleManager creates and manages particles based on current SurfacePreset settings.

• Particles are emitted on per-wheel basis. Total surface particle count is a sum of particle counts from all the wheels' ParticleSystems.
• Lateral Slip Threshold and Longitudinal Slip Threshold under Settings tab determine the lowest wheel slip threshold needed for wheel to be considered to be slipping. This affects particle effects.
