About FgearEffects:
I can’t find a way to leave the engine sound on if I enable the “Stop Effects When Sleeping” option.
(From vr 1.7 notes: A sleeping vehicle will pause its sfx and particle effects. Muting the engine sound is optional.)
Particle effects are quite expensive on mobile platforms, it would be nice if we could enable and disable the use of “tire smoke” at runtime, according to the capacity of the player’s device (as is already possible with skidmarks).
I think it would also be interesting (perhaps to avoid wasting processing resources) to have the option of deactivating other effects if we don’t use them, such as “Backfire” and even the engine sound system, if we choose to use another one, like fmod for example.
Another suggestion would be to add a quick fade both when starting and stopping the engine, it is very abrupt.
