The shader (part of the CobraFX suite ) is a specialized post-processing tool for ReShade that mimics professional camera long-exposure photography. Unlike standard real-time motion blur, it accumulates and blends actual game frames over a set duration to create authentic light trails and motion effects. Key Features & Performance
The effect is not a "one-click Instagram filter." It is a performance art that requires timing, stability, and a deep understanding of how light blends over time.
Let the frames accumulate for 5–10 seconds. You will see the movement (water, fire, or grass) slowly turn into a smooth, misty texture. Pro Tips for Better Results reshade long exposure
| Parameter | Initial Value | Description | | :--- | :--- | :--- | | | 16 | Higher = more silky water/light trails (32 is max, but heavy FPS drop) | | Blend Mode | Additive (for lights) / Linear (for water) | Additive creates bright streaks; Linear creates smooth flow | | Decay Speed | 0.85 | How fast trails fade. Lower = shorter trails. Higher = longer, ghostly trails. | | Exposure Compensation | -1.5 | Because adding 16 frames makes the scene extremely bright. Reduce exposure to match the original scene's brightness. |
: Right-click the "Start Exposure" toggle and assign it to a key (e.g., N ). This lets you trigger the effect exactly when needed . 3. Capturing the Shot RealLongExposure
Not all ReShade presets are created equal. You cannot achieve long exposure with just SMAA.fx and LUMASHARPEN.fx . You need specific accumulation shaders.
