Press Release - Geo STUDIO Pro 4.1 Released

Carbon Graphics Announces Geo STUDIO Pro 4.1 — Major Advancements in Aechelon HIE Support, GLTF Workflow, and Simulation-Driven Content Creation.

Santa Rosa, California – April 2026 — Carbon Graphics today announced the release of Geo STUDIO Pro 4.1, the latest version of its professional 3D content creation tool designed specifically for the Modeling, Simulation & Training (MS&T) market.

Building on Geo STUDIO’s reputation as a modern alternative to legacy tools, version 4.1 delivers significant enhancements in Aechelon HIE format support, GLTF interoperability, and simulation-driven scene behavior, enabling developers to create more accurate, performant, and interactive real-time content.

Next-Level Aechelon HIE Integration

Geo STUDIO Pro 4.1 introduces comprehensive updates aligned with the latest Aechelon pC-Nova image generator format, including:

• New DepthBufferGroup and NamedSwitch nodes for advanced runtime rendering and visibility control

• Expanded Switch node behavior with support for named tokens such as Time of Day, Weather, and Analog Controls

• Full support for 64 analog control variables and simulation-driven state management

• Enhanced collision types, special effects flags, and attachment point handling

These improvements ensure that Geo STUDIO remains one of the most complete authoring environments for Aechelon-based workflows, with native support extending across both import and export pipelines.

Smarter Scene Behavior & Environmental Control

Version 4.1 introduces a powerful new Environmental Settings system, enabling artists and engineers to preview simulation-driven behavior directly within the editor.

• Real-time control of Time of Day, precipitation, fog, and lighting states

• Accurate preview of NamedSwitch and Switch node behavior

• Improved parity between authored content and runtime simulation results

This brings Geo STUDIO closer to a true WYSIWYG simulation authoring tool, reducing iteration cycles and guesswork.

Enhanced GLTF Pipeline and Cross-Format Workflows

Geo STUDIO Pro 4.1 significantly improves interoperability with modern pipelines:

• Correct rendering of transparent GLTF meshes via automatic sorting

• Seamless GLB texture extraction and export across formats

• Improved scene graph fidelity during import/export

• New options for Y-up conversion and LOD export via GEO_LOD extension

In addition, exporting between GLTF, OpenFlight, and HIE formats is now more robust, enabling efficient round-trip workflows across industry-standard ecosystems.

Performance & Rendering Improvements

This release includes multiple enhancements aimed at runtime efficiency and visual accuracy:

• Automatic conversion to triangle strips for optimized HIE export

• Improved handling of multi-texture and UV set workflows

• Correct calculation of shared vertex normals for triangle meshes

• New QUALITY-based LOD nodes for simulation-driven rendering control.

Advanced Billboard & Geometry Handling

Geo STUDIO Pro 4.1 modernizes billboard and geometry workflows:

• Unified Billboard Type properties across geometry and group nodes

• Automatic camera-facing orientation based on model up-axis

• Improved OpenFlight compatibility with direct mapping of billboard behaviors

Workflow & Usability Enhancements

• Non-modal Material Editor for real-time scene interaction

• New Delete Unused Materials plugin for cleaner asset management

• Improved high-DPI UI scaling (3K/4K displays)

• Numerous bug fixes and stability improvements

Simplified Licensing for Secure Environments

Recognizing the needs of defense and secure simulation environments, Geo STUDIO Pro 4.1 introduces a streamlined offline licensing workflow:

• Generate a request file on the target machine

• Receive a secure license file from Carbon Graphics

• No network connectivity required

This makes deployment in air-gapped and classified environments significantly easier.
