Particle effect that changes parameters based on the engine state. Requires an engine to be attached to the same object.

Interpolates between Normal Color and Soot Color based on engine state, while the Lifetime Distance determines the maximum distance a particle can travel from the starting position.

A ParticleSystem prefab called ExhaustSmoke is included with the asset under NWH ⇒ Aerodynamics ⇒ Effects ⇒ Particles ⇒ Prefabs ⇒ ExhaustSmoke.prefab and can be a good starting point to configuring the exhaust ParticleSystem.
