XGRIDS Pro Guide™ / Module 9: LCC Studio

Field Guide: LCC Studio

Pipeline overview, configuration decisions, export format selection, and critical warnings for LCC Studio 3D Gaussian Splatting processing across all XGRIDS devices.

Section 1

LCC Studio Pipeline at a Glance

LCC Studio processes scan data from all four XGRIDS devices into 3D Gaussian Splatting models. It does not produce point clouds. The LCC pipeline and the LixelStudio pipeline start from the same raw scan data but produce fundamentally different outputs with no conversion path between them.

Device support in LCC Studio: L2 Pro and K1 are fully supported across all reconstruction modes. PortalCam is fully supported across all modes (Map Fusion enabled). K2 is supported in Single Model reconstruction only, including Spatial Recognition, with a 90-minute single-scene capture cap. K2 is not currently supported in Map Fusion, Aerial-Ground Fusion, or HD Enhancement; expanded K2 support is planned for a future release.

Configuration Quick Reference

Quality Settings

Three reconstruction quality presets balance processing time, VRAM consumption, and visual fidelity. Match the setting to deliverable requirements.

Quality

Use Case

Notes

Fast

Internal previews, draft client reviews

Lowest VRAM and fastest reconstruction. Lower signal-to-noise ratio than Standard. Not appropriate for final delivery.

Standard

Default for first-attempt processing and most client deliveries

Recommended starting point. Balances quality with processing time. Approximately 20:1 processing time ratio on recommended hardware.

Slow

Final deliverables requiring maximum visual fidelity

Significantly increases VRAM consumption and processing time. Highest signal-to-noise ratio. Use only when project budget supports the extended runtime.

Key Settings Decision Table

The settings below are configured at project creation and cannot be changed without reprocessing. Confirm each setting against project requirements before clicking Start.

Setting

When to Adjust

Default

Max Gaussian Splats

Consumer GPU in Single Model mode: keep below 25M to avoid VRAM overflow. Map Fusion and Aerial-Ground Fusion auto-adjust per chunk, so values above 25M have minimal effect.

25M

Portability

On for web or mobile delivery (reduces file size, improves cross-device performance). Off for desktop-only delivery with realistic lighting. USDZ export requires Portability Off.

RTK Data

Auto (default) prioritizes RTK data; auto-disables if anomalies detected. Disabled if RTK is causing instability. Disabling removes absolute coordinates and prevents Map Fusion via RTK.

Auto

Special SLAM Mode

Auto (recommended) for most scenarios. Robust for environments with vibration or interference. None for stable devices and clear environments. Narrow Scene for tunnels, mine shafts, and long corridors only.

Auto

PPR (Point Cloud Participation Rate)

Lower if sky bleeding occurs at tree or building edges in outdoor scenes. Bleeding typically results from limited capture angles, not PPR alone. Capture from multiple angles and heights for best results.

Normal

Exposure Optimization

Enable only when floating artifacts appear in scenes with dramatic lighting changes (indoor-to-outdoor transitions). May cause slight detail degradation in very bright or dark areas.

Off

Low-Memory Mode

Enable only if reconstruction fails due to insufficient RAM. Single Model mode only. Offloads intermediate data to disk; extends processing time but improves stability.

Off

Section 3

Export Format Quick Reference

LCC Studio exports 3D Gaussian Splat models in seven formats. Choose based on the downstream platform and visual fidelity needs.

Format

Best For

Notes

LCC

Default for XGRIDS ecosystem delivery (LCC Studio, LCC for BIM, XGRIDS SDKs)

Proprietary compressed format. 70 to 90% smaller than PLY. Required for LCC for BIM Revit plugin.

LCC2

Smaller files and smoother rendering for the XGRIDS ecosystem

Next-generation LCC format introduced. Editing features (Selector, Crop, Color Grading) are not yet available for LCC2.

PLY

Third-party 3DGS tools and broad compatibility

Open standard 3DGS format. 5 to 10 times larger than LCC. Use when delivering to platforms that do not support LCC.

USD

NVIDIA Omniverse with ray-traced rendering

Exported via NVIDIA 3DGRUT toolchain. Supports Omniverse Kit 110.0+ and Isaac Sim 5.0+. Does not render in Blender, Maya, Houdini, or Cinema 4D.

USDZ

NVIDIA Omniverse forward compatibility (no ray tracing)

Via NVIDIA 3DGUT with NuRec standard. Supports Omniverse Kit 107.3+. Requires firmware 3.0+, Single Model reconstruction, and Portability disabled.

3D Tiles

WebGIS and digital twin web applications

OGC 3D Tiles 1.1 standard. Directly loadable in Cesium 1.131. Requires absolute coordinates (RTK or GCPs) and 4 million Gaussian point limit.

Mesh (OBJ / PLY)

Polygon mesh deliverables for game engines or DCC software

Optional triangular mesh export without textures. Geometry only.

Section 4

Critical Warnings

No recovery

LCC Studio cannot fix poor scan data in processing. Missing coverage, excessive drift, and insufficient loop closure are field problems. No quality setting or reconstruction mode compensates for data that was not captured correctly.

K2 reconstruction restrictions

K2 is supported in Single Model reconstruction only with a 90-minute single-scene cap. K2 cannot be used in Map Fusion, Aerial-Ground Fusion, or HD Enhancement. For multi-segment K2 projects, plan around the single-scene cap or wait for the future release that expands K2 mode support.

USDZ export prerequisite chain

USDZ export requires firmware 3.0+, Single Scene reconstruction, and Portability disabled. All three conditions must be met simultaneously. If any one is missing, the USDZ option is not available in the export panel.

3D Tiles requires absolute coordinates

A scan processed without RTK or GCPs exists in a local coordinate frame and cannot be exported to 3D Tiles. Georeferencing cannot be added after the scan.

Disabling RTK Data removes absolute coordinates

A model processed with RTK Data set to Disabled has no real-world coordinates and cannot be used in Map Fusion. This setting is appropriate only when RTK data is causing reconstruction instability.

Narrow Scene SLAM Mode will fail in normal environments

Use it only for tunnels, mine shafts, and long corridors. Using it on a standard indoor scan produces a processing failure with no useful error message.

High PPR causes edge bleeding in outdoor scenes

Sky bleeds into trees and building edges at the model boundary. Lower PPR to Normal or Low for outdoor environments. The setting cannot be changed without reprocessing.

Max Gaussian Splats above 25M can cause VRAM overflow in Single Scene

This produces memory failure, lower reconstruction stability, or degraded quality. In Map Fusion and Aerial-Ground Fusion modes, LCC auto-adjusts chunk size, so values above 25M have minimal effect.
