9.2 Single Scene Processing
How to import scan data, configure a single-scene reconstruction project in LCC Studio, select quality and settings, and review results before export.
Importing Your Data
- Transfer the raw scan folder from the device to the workstation SSD. USB transfer for L2 Pro (internal SSD) and K1 (TF card). PortalCam data transfers via the LCC Scan app export function.
- Confirm free storage space is at least 5 times the project folder size. LCC Studio writes substantial intermediate data during reconstruction. Running out of disk space mid-process corrupts the project.
- For Insta360 coloring files, verify the recording format before importing. LCC Studio requires normal video mode, not timelapse. Timelapse is for LixelStudio. Placing a timelapse file in an LCC Studio project causes a coloring failure.
- Confirm the workstation has an active network connection. The website-downloaded LCC Studio is the online version and requires network connectivity for creating models and starting processing. Viewing previously generated models in View mode does not require network.
- Keep the original data on the device until processing is verified. Do not delete device files after copying. The cost of storage is not comparable to the cost of a return site visit.
Creating a Single Scene Project
- Open LCC Studio and click Create. Select Single Scene Reconstruction from the mode options (top row in the dialog). Use Single Scene for projects captured in a single session without Map Fusion requirements.
- Name the project using a clear, consistent convention. The name is used in exported filenames and in the web publish link.
- Add the scan data folder under Ground Data. LCC Studio reads the device type from the folder contents and displays it next to the Ground Data label (shown as "PortalCam" in the screenshot).
- Set Quality. Standard is the correct starting point for all first-attempt processing. Use Fast only for previews. Use Slow for final deliverables requiring maximum visual fidelity. The three options appear under Reconstruction Settings in the right panel.
- Set Max Gaussian Splats. The Estimated RAM bar in the upper left shows projected system memory usage as you adjust this value. The Estimated VRAM bar in the upper right shows projected GPU memory usage. Stay within both bars for your system. For consumer GPUs, stay under 25M in single-scene mode to avoid VRAM overflow, memory failure, or degraded reconstruction quality. If either bar turns red, the project exceeds available capacity and reconstruction will likely fail. Reduce this value or increase system resources before proceeding.
- Set Portability. On for web or mobile delivery, reduces file size and improves cross-device performance. Off for desktop-only delivery requiring realistic lighting effects. USDZ export requires Portability Off.
- Configure Advanced Settings if needed. SLAM Mode: Robust for most environments. PPR: Normal for indoor, Low for outdoor. RTK Data: Auto (default) or Disabled if RTK is causing instability. Start-to-End Loop Closure: enable only if the scan returned to its starting point. Exposure Optimization (labeled "beta" in the interface): enable when the scan dataset contains both indoor and outdoor environments to compensate for camera exposure differences between zones.
- Enable Low-Memory Reconstruction only if the project fails due to RAM limitations. This option offloads intermediate data to disk, reducing peak RAM usage at the cost of increased processing time. It is only available in single-scene mode.
- Click Start. Close all other applications before starting, including web browsers (Chrome with multiple tabs consumes significant GPU memory), other 3D applications, video editing software, and any tool that uses the GPU. Do not run LixelStudio processing simultaneously on the same machine. LCC Studio reconstruction is GPU-intensive and competes directly for VRAM with any other running application. Background GPU tasks degrade processing quality and can cause outright failures. Do not close LCC Studio or shut down the workstation during processing. Closing LCC Studio interrupts the process and does not save progress. The SLAM phase restarts from the beginning when you reopen. Monitor progress in the LCC Studio interface.
Portability and Max Gaussian Splats affect which export formats are available after processing. Portability On disables USDZ export. Models above 4 million Gaussian points cannot export to 3D Tiles. These settings cannot be changed after reconstruction completes without reprocessing the entire project. If the deliverable requires USDZ, 3D Tiles, or a specific third-party platform, confirm format prerequisites before clicking Start. See 10.6 Platforms and File Types for the full format compatibility reference.
Processing time at Standard quality is approximately 20 minutes of compute per 1 minute of scan duration. A 5-minute scan takes roughly 100 minutes to process. A 20-minute scan takes roughly 7 hours. Plan accordingly before starting.
Processing stuck at 5.1%? That is normal. The SLAM phase can hold at 5.1% for 30 minutes or more before advancing. This is the most common processing concern reported by new users. Environments with repetitive geometry (data centers, warehouses, long symmetric corridors, parking structures) take the longest because the algorithm has fewer unique features to differentiate.
Do not close LCC Studio, restart the project, or shut down the workstation. Interrupting forces a complete restart from 0%. If the application has not crashed and the system is still responsive, processing is still active. Let it run.
Reviewing Results in the Viewer
After reconstruction, the model opens in the LCC Studio viewer. Use the viewer to verify visual quality, coverage completeness, and dimensional accuracy before exporting or publishing.
Navigation Modes
Flythrough mode uses WASD for movement and mouse for direction. Shift increases speed, Ctrl decreases it. Pivot mode rotates around a selected point with right-click panning and scroll zoom. Avatar mode simulates ground-level walking with collision detection.
- Navigate the full extent of the model and confirm all required areas are present. Missing zones cannot be recovered in post-processing.
- Check coverage at transitions, including doorways, stairwells, and areas where scanning speed may have been higher.
- Verify a known dimension using the measurement tool. A room that measures significantly differently from known dimensions indicates SLAM drift. The entire scan may have an accuracy problem that requires rescanning. LCC Studio measurement is approximate and not survey-grade. For the most reliable results, switch to Pivot mode, align the viewing angle straight-on to the measurement plane, select two clear reference lines, enable Pro Measurement Mode, and keep one of the X, Y, or Z values at 0.
- Inspect visual quality in areas that matter most to the deliverable. Equipment labels, MEP details, and fine architectural elements require adequate scan coverage from multiple angles to reconstruct cleanly.
- Check for reconstruction artifacts, including floating geometry, blurry surfaces, or areas with inconsistent density. These typically indicate zones where loop closure was insufficient or scanning speed was too high.
