SLPK Import

Convert ESRI SLPK to Open 3D Tiles

Unlock your ESRI Scene Layer Packages and bring them into open standards. Our SLPK converter extracts geometry, textures, and metadata from .slpk files and converts them to modern GLB-based 3D Tiles format.

Whether you're migrating from ArcGIS or simply need to use your ESRI data in Cesium, Mapbox, or custom viewers, our converter preserves all visual fidelity while enabling broader platform support.

Extract geometry and textures from .slpk archives
Preserve LOD hierarchies and metadata
Support for I3S versions 1.6 through 1.10
Batch process multiple SLPK files
Convert to GLB (3D Tiles 1.1+) or legacy B3DM

SceneServer

Live ArcGIS SceneServer Integration

Connect directly to ArcGIS SceneServer endpoints and convert live services to 3D Tiles. Perfect for creating offline caches or migrating from ArcGIS Online to open platforms.

Our SceneServer connector supports authentication tokens for secured services, concurrent downloads for faster processing, and intelligent caching to avoid redundant data transfers.

Connect to public and secured SceneServer services
ArcGIS token authentication support
Concurrent downloads (up to 16 parallel streams)
Local caching for repeated access
Size and feature limit controls

                        
# Convert from SceneServer

pg2b3dm-glb --data-source SLPK \

  --sceneserver-url "https://services.arcgis.com/.../SceneServer" \

  --arcgis-token "your_token" \

  --concurrent-downloads 8 \

SLPK Export NEW

Export to ESRI Scene Layer Package

Now you can create SLPK files from your 3D Tiles data! Export PostgreSQL data, CityGML models, or BIM files to ESRI Scene Layer Package format for use in ArcGIS Pro, ArcGIS Online, and ArcGIS Enterprise.

This bidirectional capability enables seamless workflows between open 3D Tiles ecosystems and the ESRI platform. Your data can flow freely in both directions.

Export 3D Tiles tileset to SLPK format
Convert FileGDB Multipatch directly to SLPK
Export GLB file directories to SLPK
I3S 1.6, 1.7, 1.8, and 1.10 format support
Configurable profiles: 3DObject, IntegratedMesh, Point

                        
# Export 3D Tiles to SLPK

pg2b3dm-glb --export-to-slpk \

  --slpk-from-tileset ./tileset.json \

  --i3s-version 1.10 \

  --i3s-profile 3DObject \

  --output ./buildings.slpk

# FileGDB to SLPK (direct)

pg2b3dm-glb --export-to-slpk \

  --slpk-from-filegdb ./data.gdb \

  --output ./scene.slpk
