The primary goal for Unrecord-style optimization is Optical Authenticity. The realism is created through “imperfections”: lens dirt, chromatic aberration, and a specific type of motion blur that mimics camera shutter speed. By refining the UE5 Lumen and Nanite parameters in the config files, we can ensure the lighting bounces naturally off scanned surfaces (photogrammetry) without the “glow” artifacts that often break immersion in standard shooters.
Hardware Compatibility & Expectations
- The “Lumen” Tax: Unrecord relies heavily on Lumen for its indirect lighting. To maintain 60 FPS, a GPU with dedicated RT Cores (RTX 3060 / RX 6700 XT or higher) is essentially required.
- Nanite and SSDs: The environment uses Nanite to render millions of polygons. Running this on a traditional HDD will cause massive “hitching” as you move through the environment.
- VRAM Bottleneck: At the highest realism settings, the game can easily push past 10GB of VRAM. If you have an 8GB card, you must use the
r.Streaming.PoolSizetweak provided below.
File Location
Since Unrecord is in active development, the config location typically follows the standard UE5 path: %LOCALAPPDATA%\Unrecord\Saved\Config\WindowsNoEditor\Engine.ini (Note: If the folder name changes upon full release, look for the “Drama” or “Unrecord” project folders.)
Best Engine.ini for Body-Cam Realism
Add or modify the following blocks to achieve the specific “low-quality high-detail” look of a digital body-cam:
[SystemSettings]
r.SceneColorFringeQuality=1 ; Essential for the "Body-Cam" lens edge blur
r.NGX.DLSS.Sharpness=0.4 ; Keeps the image from looking "too digital"
r.Lumen.Reflections.Allow=1
r.Lumen.HardwareRayTracing=1 ; Enable if your GPU supports it for true realism
r.Shadow.DistanceScale=2.0 ; Prevents shadow "pop-in" which ruins the illusion
r.MotionBlur.Amount=0.3 ; Mimics a real camera's shutter speed
r.Streaming.PoolSize=4096 ; Set to 50% of your VRAM (e.g., 4096 for 8GB cards)
[/Script/Engine.RendererSettings]
r.Nanite.MaxPixelsPerEdge=1.0 ; Maximizes Nanite detail for photogrammetry
r.DefaultFeature.AntiAliasing=2 ; Uses TSR (Temporal Super Resolution) for stability
r.PostProcessAAQuality=4
r.BloomQuality=1 ; Keep low to avoid "dreamy" look; real cams have subtle bloomPro Tip: The secret to the Unrecord look is Fisheye Distortion. If the game doesn’t have an in-game slider for this, it is often handled by a “Post-Process Material.” In the config, ensuring
r.SceneColorFringeQuality=1(Chromatic Aberration) is the first step toward that distorted camera-edge effect.
Key Parameters Explained
| Parameter | Recommended Value | Impact |
| r.Nanite.MaxPixelsPerEdge | 1.0 | Forces the highest level of geometric detail on scanned walls and floors. |
| r.SceneColorFringeQuality | 1 | Adds the slight “color bleeding” on the edges of the screen typical of cheap lenses. |
| r.Lumen.HardwareRayTracing | 1 | Uses the GPU’s ray-tracing cores to calculate light, essential for realistic dark interiors. |
| r.MotionBlur.Amount | 0.3 | Provides the “smoothness” seen in the trailer without making the player feel motion sick. |
Visibility vs. Realism (Tactical Tuning)
To match the trailers, use these strategies in the In-Game Settings:
- Sharpness: Do not set this to 100%. Real body-cam footage is often slightly soft or “noisy.” Aim for 30-50%.
- Global Illumination: Set to Epic. This enables the full Lumen bounce, which is what makes the light in the “abandoned building” scenes look like real life.
- Depth of Field: Enable. This helps simulate the camera focusing on the weapon or a close-range target, blurring the background slightly.
Troubleshooting & Common Fixes
- Grainy Shadows: This is a byproduct of Lumen. If shadows look like “moving dots,” increase
sg.ShadowQualityto Epic or enable Hardware Ray Tracing in the.ini. - Motion Sickness: The “Body-Cam” sway is intense. If you feel ill, look for the “Camera Shake” or “View Bob” settings in the menu and reduce them to 25%.
- Texture Pop-in: Ensure
r.Streaming.FullyLoadUsedTextures=1is added to yourEngine.iniif you have a fast NVMe SSD.
Frequently Asked Questions (FAQ)
Is Unrecord “too real” because of textures?
Actually, it’s because of the Camera Movement. The camera is parented to the player’s chest/head with physics-driven “springs.” This makes the movement feel like a human walking rather than a floating camera.
Can I run this on a GTX 1080?
It will be very difficult. Without hardware support for Lumen (Ray Tracing), the game has to use “Software Lumen,” which is very CPU-heavy and lacks the mirror-like reflections seen in the trailers.
Does the “Body-Cam” effect hide low-quality assets?
Partially. The lens distortion and grain help mask lower-resolution textures, but Unrecord specifically uses Photogrammetry (scanned real-world locations), so the assets themselves are incredibly high-quality.
Conclusion and Expected Results
By manually refining your Engine.ini for UE5’s advanced features, you are leaning into the “imperfect” aesthetic that makes Unrecord look like real footage. You can expect highly realistic light transitions between indoor and outdoor areas, sharp geometric detail on all surfaces thanks to Nanite, and the signature ‘distorted lens’ look that defines the body-cam genre.
