Capture settings and troubleshooting

Available capture settings

You can tune these in NGDCRenderingSettings and NGDCExportSettings:

• UpscalingRatio: Sets the ratio between jittered input and ground-truth output. Fractional values are supported.
• SupersamplingRatio: Controls quality/performance tradeoff while capturing.
• FixedFrameRate: Locks capture frame rate when greater than 0.
• CameraCutTranslationThreshold and CameraCutRotationThresholdDegrees: Heuristics for marking camera cuts when needed.
• DatasetDir and CaptureName: Control output folder location and capture name.

Recommended system specification

For smooth out-of-box capture, a representative spec is:

• RAM: 64 GB
• GPU: NVIDIA GeForce RTX 4080 (driver 572.96 or newer)
• OS: 64-bit Windows or Linux

Common issues and solutions

Plugin not detected:

• Confirm plugin is under your project Plugins/ directory.
• Regenerate project files and rebuild.

Hotkeys don’t work:

• Verify Level Blueprint has C wired to Begin Capture and V wired to End Capture.

Dataset folder is empty:

• Confirm capture started and that export path is writable.

Stutter or instability:

• Lower SupersamplingRatio and test again.

Unexpected output size:

• Use Standalone Game mode instead of New Editor Window (PIE).

What you’ve learned

You’ve successfully set up a workflow to capture neural graphics datasets directly from Unreal Engine 5.5 gameplay. You can now:

• Generate training data from your own game content without graphics API configuration
• Capture representative gameplay sequences with real motion and camera behavior
• Export frame datasets ready for use with Model Gym’s NSS data generation pipeline
• Tune capture settings to match your specific quality and performance requirements

Use this repeatable workflow for model experimentation and evaluation in your neural graphics pipeline.
