A car on a display stand and a car in a race live under different conditions. On the stand, you can choose the light and angle. On the track, there are rivals, effects, repairs, jumps, and the player’s saved choices. The final part of this Smoke and Flame retrospective follows the bone car across that boundary.

As of October 11, the model is connected to the garage and race, while the revised proportions and effects are still being evaluated after feedback. This is local prototype work. We’re not announcing a public game release or applying results from a separate test stand to the performance of the whole race.

Smoke should come from the exhaust pipes

During integration, effect points were aligned with the actual construction. The previous set of sources was replaced by the outlets of two side pipes. The latest refinement added black smoke: faint at idle, thicker under load and with nitro, with no flame jet.

Pausing stops the effect, and recovery clears the trail. During engine service, smoke is turned off. These states prevent odd artifacts, such as a long line across the scene after the car moves.

Stone leaves a different mark

The four stone-wheel contact points draw thin grooves instead of rubber tire marks. There should be no scratches in the air or when the wheels aren’t in contact with the road. Other cars keep their own effects. The difference makes material part of the movement without changing the whole garage for one design.

After reviewing the marks, the pattern was refined further: regular short strokes looked too much like tread. This is the kind of change that’s hard to assess with a number alone. You need an actual frame of the car moving on the road.

Repairs bring the model back, too

Full runs included a pit stop and wheel restoration. After repairs, the parts need to return to the right axes with the right materials. The team also checked weapons, recoloring, saves, and completing a lap with rivals.

Earlier performance drops aren’t considered fixed just because the latest change passed its checks. A current measurement is needed to make that claim. That brings this series up to the present stage: the car has left the stand, but it’s still receiving specific feedback in the game. Future devlogs will continue from the evidence—real frames, results, and the changes the road actually calls for.
