Ride 6: Best Engine.ini for Bike Reflection Detail

The objective is to eliminate the “grainy” look of reflections on metallic surfaces and increase the distance at which high-quality reflections are calculated.

File Path & Setup

1. Navigate to: %LocalAppData%\Ride6\Saved\Config\WindowsNoEditor\Engine.ini
2. Backup: Copy your existing file before making changes.
3. Pro Tip: After saving, right-click Engine.ini and set it to Read-only to prevent the game from resetting your custom variables when you enter the graphics menu.

Optimized “Mirror Finish” Configuration Table

Parameter	Recommended Value	Technical Purpose
r.Lumen.Reflections.HardwareRayTracing	1	Forces Hardware Ray Tracing for reflections if your GPU supports it.
r.Lumen.Reflections.MaxRoughnessToTrace	0.4	Increases the threshold for what surfaces get dedicated rays ($R_{smooth}$).
r.SSR.Quality	4	The Master Fix. Maxes out Screen Space Reflection fidelity.
r.GBufferFormat	5	Enables High Precision Normals (16-bit) for smoother reflections.
r.RayTracing.Reflections.SamplesPerPixel	2	Reduces “denoising artifacts” on curved surfaces.

HowTo: Engineering the Ultimate Reflection Build

Follow these GameEngineer.net technical steps to transform your bike’s visuals:

1. Enabling High-Precision Normals: Under the [SystemSettings] section, add r.GBufferFormat=5. This is crucial for motorcycles; without it, the curved surfaces of the fuel tank and fairings can show “banding” in reflections ($B_{band}$).
2. Lumen Hardware Override: Setting r.Lumen.Reflections.HardwareRayTracing=1 ensures that reflections are calculated against the actual geometry of the world, not just the “Screen Space” information. This means you’ll see buildings and other riders reflected even if they are behind your camera view.
3. Refining Surface Roughness: Use r.Lumen.Reflections.MaxRoughnessToTrace=0.4. By default, UE5 stops tracing rays on slightly matte surfaces. This tweak ensures that even the plastics and rubber on your bike catch subtle light reflections.
4. Increasing SSR Fidelity: While Lumen is the star, Screen Space Reflections (SSR) handle the “immediate” contact reflections. Setting r.SSR.Quality=4 and r.SSR.Temporal=1 removes the flickering often seen on wet tracks.
5. Denoising Clean-up: Adding r.Lumen.Reflections.Temporal.MaxFramesAccumulated=10 helps smooth out the reflection over time, eliminating the “sparkling” effect on metallic paint jobs when moving at high speeds.

[SystemSettings]
r.GBufferFormat=5
r.Lumen.Reflections.HardwareRayTracing=1
r.Lumen.Reflections.MaxRoughnessToTrace=0.4
r.Lumen.Reflections.Temporal.MaxFramesAccumulated=10
r.SSR.Quality=4
r.SSR.Temporal=1
r.RayTracing.Reflections.SamplesPerPixel=2
r.RayTracing.Reflections.MaxRoughness=0.6
r.SceneColorFringeQuality=0

Technical Explanation: Ray Accumulation and Roughness Thresholds

In Ride 6, the engine must decide which pixels are “shiny” enough to deserve a ray trace. This is the Roughness Threshold ($T_{rough}$).

$$Reflection_{fidelity} = \frac{Samples_{ray} \times Precision_{GBuffer}}{Roughness}$$

By engineering the Engine.ini, we lower the denominator (allowing rougher surfaces to trace rays) and increase the numerator (using 16-bit GBuffer precision). This ensures that light doesn’t just “hit” the bike; it wraps around the curvature of the frame and engine components, providing the depth and “wet look” that characterizes high-end motorcycle photography.
