Module 9 Quick Field Guide

LCC Studio at a Glance

LCC Studio turns XGRIDS scan data into 3D Gaussian Splatting models. It does not produce point clouds, and there is no conversion path to or from LixelStudio. If the job needs a measured point cloud, process the raw data through LixelStudio instead.

Editions. The free edition covers Single Model reconstruction, the full viewer and editor, web publishing with cloud access management, camera path recording and flythrough export, and export to LCC and LCC2. The Premium edition adds five capabilities and three formats: Map Fusion, Aerial-Ground Map Fusion, Aerial Reconstruction, HD Enhancement, Spatial Recognition, and export to PLY, USD, and 3D Tiles.

Devices. L2 Pro is supported across the reconstruction modes. K2 is supported across the modes, including Map Fusion and Aerial-Ground Map Fusion. PortalCam is supported across the modes, including Map Fusion and Aerial-Ground Map Fusion, with Layering Optimization on by default.

Load capture data by connecting the device over USB and letting LCC import it, which is the cleanest path. If you load by hand, select the main capture project folder the device created, not a sub-folder, and keep the project and backup paths on an SSD that is separate from the install directory.

Reconstruction Mode Selector

Choose the mode on the My Models page when you create the project. The mode is fixed at reconstruction.

Settings That Lock at Start

Every setting below is set at project creation and locks when you click Start. Changing one means reprocessing the whole scan, so confirm each first.

Numbers and Limits to Remember

Pre-Reconstruction Checklist

Run this before you click Start. Most items cannot be fixed afterward without reprocessing or a return to the site.

• Mode chosen before loading. It locks at Start.
• Paths set for the project and the capture backup, on an SSD, separate from the install directory.
• Disk reserved: at least 2x the capture size free.
• Right folder loaded: the main capture project folder, not a sub-folder. USB auto-import is cleanest.
• Floor plan decision made: if you need one, check Spatial Recognition now. It cannot be added later.
• Fusion control confirmed: for Map Fusion or Aerial-Ground, every ground segment carries RTK or control points. Uncontrolled scans are rejected.
• Drone RTK setting matched to what the drone actually recorded, on aerial jobs.
• Point Cloud Preview run: it checks the data and flags fixable capture problems before you commit hours.
• Locked settings confirmed: Quality, Portability, Maximum Gaussian Points, Coordinate System Conversion, and any device options.
• Do not close LCC Studio once reconstruction starts. Closing interrupts the job.

Navigate a Finished Model

The viewer toolbar carries Switch View, Camera Speed, Origin Point (reset to capture start), Point Cloud, Collider, Height Filter, Screenshot, Grid, Capture Trajectory, and Environment Data. Full detail is on 9.8 LCC Studio Tools.

Author a Tour: Quick Numbers

Full authoring workflow is on 9.9 Scene Editor Tools and 9.12 Virtual Tour Workflow.

Deliver

You do not export a file to share a tour. You publish, and the link LCC returns is the tour. Your client opens it in a browser with no install. Export is only for handing the file to someone who needs it in another program.

1. Click File, then Publish, or use the quick-publish button on the project card.
2. Choose access. Password-Free lets anyone with the link view. Encrypted requires a password, custom or system-generated.
3. Add a model description for context, such as address, project name, and scan date.
4. Click Create, then Share to copy the link and password. Manage links later in Publish Management.

Export format quick reference

Select the model card, click the ... button in its upper-right corner, and choose Export. The free edition writes LCC and LCC2. PLY, USD, and 3D Tiles require Premium.

Two things people miss

• Converter, for batch work. LCC Studio converts between 3DGS formats in bulk, including batch conversion to LCC2, and outputs to 3D Tiles and USD. Use it when a finished library needs a new delivery format, rather than exporting one model at a time.
• Creator Data, free, after reconstruction. Available for L2 Pro, K2, and PortalCam data: original and undistorted images, invalid masks for both sets, camera intrinsic and extrinsic parameters for both sets, device poses, and the optimized laser point cloud. This is what simulation, photogrammetry, and machine learning pipelines ask for, and the finished model alone cannot supply it. Scope it in the contract before you hand it over, because it carries different licensing weight than a viewable model.

For access-control choices by audience and the full format detail, see 9.7 Export Formats and 9.12 Virtual Tour Workflow.

Critical Gotchas

• No recovery from poor scan data. Coverage gaps, drift, and weak loop closure are field problems. No setting fixes them in processing.
• Settings lock at Start. Changing one means reprocessing the whole scan.
• Map Fusion rejects any segment that has neither RTK nor a control point. Overlap and visual features alone do not admit a segment, the link cannot be added after capture, and an uncontrolled scan must be recaptured.
• An RTK ground scan does not rescue a non-RTK drone. Pairing an L2 Pro RTK scan with a drone that has no RTK is the one combination XGRIDS advises against. It often fails as layer separation rather than an error, so it can pass a quick review and reach the client.
• Floor plans need Spatial Recognition on before processing. It cannot be added afterward.
• Closing LCC during reconstruction interrupts the job. Reopen and use Continue Generation or Restart Generation. Pausing is different: use the pause button on the model card and the job resumes from the breakpoint.
• 3D Tiles needs RTK absolute coordinates. Georeferencing cannot be added after the scan.
• HD Enhancement needs at least 20 photos at every enhancement point. Meeting the project total while starving one point is what causes the failures.
• Narrow Scene SLAM fails in normal spaces. Use it only for tunnels, shafts, and long corridors.
• High PPR bleeds sky into outdoor edges. Lower it for outdoor scenes.
• Maximum Gaussian Points above 25M can overflow VRAM in a single model.
• Layering Optimization on a repetitive layout can misalign the model. Turn it off for cubicles or identical floors.
• Confirm the client's delivery format before you assume Premium is required. LCC2 and the published link are both free-edition outputs. Premium is what buys PLY, USD, and 3D Tiles.
• Coordinates without their EPSG code are unusable. Send the code with any coordinates you hand over, and round to the accuracy the job actually delivered. The readout prints far more decimal places than the data supports, and the extra digits get read as a claim.
• The EPSG code covers the horizontal system only. It names no vertical datum, so the height value arrives with no stated reference attached. Confirm what it is referenced to before quoting an elevation to a surveyor or putting one on a deliverable.
• LCC does not transform between coordinate systems. It reports the system the model was built in. Latitude and longitude, or a local grid such as a state plane zone, means running the raw data through LixelStudio. Confirm the client's working system before the handoff, not after.
