We are thrilled to announce Trian3DBuilder Major Release v9.0 – a major step forward in performance, stability, and future-proofing
This release goes far beyond incremental improvements, introducing deep architectural changes, designed to help professionals generate complex terrains faster, smarter, and more efficiently, while expanding export capabilities to modern platforms.
New Threading Model:
One of the core pillars of this release is the new threading model, designed to fully leverage modern multi-core architectures. Now using multiple threads for each terrain tile for high generation performance, the results are striking:
- Up to 60% lower memory usage
- Up to 50% faster generation times
- Significantly improved CPU utilization
- Reduced I/O load and increased stability
Generation times for specific terrain for CDB with 16 threads
New Modifier Pipeline:
The modifier system has been rebuilt in a modern, high-performance processing pipeline architecture, allowing parallel execution of modifiers.
The result: lower memory usage and higher performance without requiring any project changes.
New Terrain Mesh System:
Now offering a broader choice of different mesh systems to better match your project requirements:
- Chunk Mesh System – Previous system which recursively divides the cells for incisions based on a regular grid
- Maritime Mesh System – Specially designed for processing nautical charts
- The new Delaunay Mesh System – a new optimized system based on Delaunay triangulation
- Fewer triangles when cutting
- Faster processing
- Up to 90% lower memory usage

Right: Delaunay with minimal intersection points
Rail Infrastructure Support:
Trian3DBuilder 9.0 also extends its capabilities to professional railway infrastructure modeling. Key features include:
- Rails with 3D profile and track bed
- Switches with open/closed status
- Support for tunnels, bridges, and railroad crossings
- Transitions to roads without track beds and flat rails for trams
- Overhead lines
Rail traffic logic can be exported to OpenDRIVE and railML (version 3.3)
As a member of railML.org, TrianGraphics supports standardized data exchange for rail systems.
Building Modifier Enhancements:
The Building Modifier has been extended to provide greater flexibility in building generation.
- Facade textures can now be adjusted per side using Local Overrides
- Material tags in the Library allow assigning equally tagged elements from material groups, ensuring a consistent look across building levels
Exporters- faster & smarter pipelines:
New FlightGear Exporter
Export Terrain, assign FlightGear materials, models, and lights directly to FlightGear 2022.
Helgoland, Germany, with OSM data in Trian3DBuilder
Helgoland, in FlightGear
CDB
- Several enhancements in performance generation
- Support for bathymetric elevation layers, enabling underwater terrain generation
Unreal Engine
- Widget optimization for Unreal Engine, resulting in better dialog integration and faster imports thanks to reduced memory usage
Trian3DBuilder 9.0 is not just an update – it is a structural evolution
With a new threading model, the addition of the Delaunay-based terrain mesh system, and the several enhancements to the export workflows, this release establishes a new benchmark for high-performance 3D terrain generation.
