SiEGA – Release Notes
Welcome to the official release history of SiEGA.
v2.2.0 - Scene Creation & Exploration Update
Version 2.2.0 – [March 06, 2026]
We’re back with a brand new major release for SiEGA. This update introduces several powerful new tools and workflows that significantly expand how users can build, present, and interact with their scenes. Alongside these additions, we’ve continued improving performance and refining existing systems across the platform. You can find the full list of changes below.
🚀 New Features
Asset Library: The new Asset Library provides an intuitive workflow for browsing and utilizing SiEGA's asset inventory. Users can explore asset categories, select individual assets, and place them directly into the scene. Once placed, assets can be freely moved, rotated, scaled, or removed as needed, allowing users to efficiently populate environments while maintaining flexibility and consistency across their projects. Multiple instances of the same asset can also be placed to rapidly build out complex scenes. The ability to save and load assets loaded through the asset library is still a work in progress. This should be completed by the time our next patch rolls out.
Cross Section: The Cross Section feature allows users to dynamically explore 3D environments by introducing an adjustable clipping plane into the scene. When activated, a movable plane is spawned that can be positioned and rotated using the standard selection tools. As the plane is manipulated, all Cesium 3D assets in the scene—including world terrain—update in real time to reveal a cross-sectional view. This allows users to inspect interior structures, subsurface elements, and spatial relationships with greater precision and clarity while navigating complex geospatial environments.
Virtual Reality Mode(experimental): Virtual Reality Mode allows users to explore their SiEGA environments in a fully immersive VR experience using a supported headset. When activated, users can navigate their scene in either Fly Mode or Walk Mode, enabling both free aerial movement and grounded exploration at a human scale. This provides a more intuitive way to inspect environments, understand spatial relationships, and interact with large geospatial datasets from within the scene itself. Please note that VR Mode is still a work in progress, and users may encounter bugs or unexpected behavior as we continue improving and expanding this feature. Confirmed supported headsets currently include Meta Quest 2 and Meta Quest 3.
Stories: Story Mode enables users to create guided, narrative-driven experiences through a configurable slideshow system. Users can build a sequence of slides tied to specific locations in the scene. During playback, the camera automatically teleports to each slide’s location, presenting the content in a structured and immersive format. Each slide can include custom descriptions and individually configured durations, allowing users to control the pacing and context of their presentation. Slideshows can also loop automatically for continuous playback.
Media in Data Layers: Images and videos can now be imported directly into the world through the Media system. Images containing EXIF metadata with latitude, longitude, and altitude will automatically be placed in their correct geospatial location using the Presentor object. Multiple images can be imported simultaneously, with only those containing location data positioned automatically. Videos can also be imported and attached to Presentor objects, which can be manually placed within the scene for flexible media positioning.
Tile Compare: The Tile Comparison feature allows users to visually compare two assets within the same scene using an interactive split-screen workflow. After selecting two assets to link together, a movable slider divides the viewport, displaying each asset on its respective side. As the slider is adjusted, the boundary updates in real time, enabling direct visual comparison even when the assets occupy the same physical location within the environment.
Point Cloud: Users can now edit the colors of classifications for Cesium 3D Tileset LiDAR Point Clouds. Adjusting the color of a classification ID updates the appearance of all points belonging to that classification globally across the scene. This feature expands on the ability to classify Cesium-streamed LiDAR datasets and allows users to better visualize and distinguish different point cloud classifications.
Terrain and GeoJSON from Cesium: Terrain datasets and GeoJSON layers can now be streamed directly from Cesium ion, allowing users to quickly integrate geospatial terrain data and vector overlays into their projects.
🔧 Improvements
New Globe Pawn: The fly mode controls have been heavily redesigned, resulting in smoother and more responsive movement. The updated implementation significantly improves the overall feel of navigation while reducing issues associated with the previous system. Users can now use WASD + EQ to move throughout the scene, controls that most gamers should be very familiar with. Users can also tap the "T" button to toggle touch mode.
Settings for 3D Tilesets: Expanded settings have been added for working with streamed Cesium assets. Users can now enable and configure classification directly within the settings menu for 3D Tilesets, as well as adjust attenuation parameters such as geometric error scale, maximum attenuation, and base resolution. Additional configuration options are also available for Cesium GeoJSON assets, including outline visibility, styling controls, and random color variations based on a selected base color.
The old username and password login method has now been deprecated. From now on, clicking the login link will open an external browser tab, prompting you to log in with an account registered at aeroai.io.
Media has been renamed to Bookmarks. This feature was previously located in the Actions menu and has been renamed to better reflect its intended functionality.
Locally imported LiDAR point clouds now support Eye Dome Lighting, improving depth perception and visual clarity when viewing dense point cloud datasets.
Made the full screen feature when playing videos in bookmarks more lenient to small mouse movements.
Added scaling options to the CAD import process.
🐞 Bug Fixes
Blocked an exploit that could allow the fly pawn to get underneath the surface of the globe.
Resolved a bug where clicking the "Esc" key multiple times would cause multiple exit game menus to appear.
Collapsed more menus when loading a new save state.
Resolved an issue with playing videos that would happen when switching to another pawn.
🐛 Known Bugs
VR Mode is currently experimental and may contain bugs or unexpected behavior.
Selecting Gaussian Splats in select mode not working as intended.
Occasionally, thumbnails on media images are incorrect.
Fatal Error occasionally appears when exiting the application using the exit button in the actions menu.
Viewshed will occasionally stop working, users wont be able to place more viewsheds.
Panning with the cursor on a locally spawned LiDAR Point Cloud can cause the cursor to get stuck to the model.
Exiting VR Mode may disrupt normal application functionality. If this occurs, restarting SiEGA will restore normal operation.
VR Walk Mode orientation may become inconsistent after teleporting. Physically rotating your headset can help realign the viewing direction.
Placing a MetaHuman from certain camera angles may cause the asset to briefly move toward the camera during placement. This behavior only occurs while placing the asset. Once placed, the MetaHuman will remain in the intended location.
Clearing the rotation or scale fields when placing multiple assets does not reset the values. To restore the default settings, users must manually set the scale to 1,1,1 and the rotation to 0,0,0.
Asset rotation persists between placements in the Asset Library. Once a rotation value has been set, all subsequently placed assets will use the same rotation. Clearing the input fields will not reset the value; users must enter 0,0,0 to return to the default rotation.
🔮 Coming Soon
Cloud Saving: Will allow streaming users to be able to have persistent saves, even over the cloud. For teams in the same organization, members will be able to share save slots across the organization. Current local saving is still a work in progress. Please be advised that not all features are fully integrated into the saving system yet. This feature is actively in development.
Artificial Intelligence Assistant: There will be an AI Assistant who will be there to assist you through SiEGA at any moment. Further developments to this feature may also include ways to enhance the SiEGA environment through advanced image, video, and model generation.
Timelines: 4D Model Visualization which will allow users to view changes over a course of time in a 3D environment.
AI Image and Video Enhancements: Take screenshots and videos in SiEGA and use a prompt to enhance them. Then export the content however you'd like!
As always, we’re hard at work making SiEGA better every day. If you’d like to share feedback or leave a remark, feel free to reach out anytime through our socials or on Discord.
That’s all!

v2.1.0 - GeoJSON, Gaussian Splats, New User Interface, and more!
Version 2.1.0 – [August 6, 2025]
Hey everyone! We're back, a little later than expected, but with a new major version, and a lot of massive changes! The first thing you will notice when opening up SiEGA now, is that the user interface has been completely overhauled. We decided to move many of our pop-up overlays into sidebars on the left, bottom, and right. This should feel a lot more comfortable to many users as it mimics more traditional editor-styled applications. To our experienced SiEGA users, we promise you'll like this new version much more! We've also made some big improvements with ways you can now visualize data, which we'll go in depth about below.
🚀 New Features
New User Interface: We've moved all of the popup overlays to sidebars on the left, bottom, and right sides of the screen. This creates a more editor-style application experience, and overall just prevents the main view port from getting too cluttered. These sidebars are resizable and allows users to do a lot more without getting overwhelmed.
GeoJSON Visualization: GeoJSON files can now be imported locally from your computer's hard drive and visualized over areas.
Local Imagery Import: Create imageries through Cesium Ion and overlay them on the globe in SiEGA through the Data Layers Panel.
Presenter Tool: Add your own images and videos to a presenter tool, which can be placed anywhere in the world. Clicking on the presenter icon will show a window with the media that you uploaded.
CAD Imports: Upload various types of CAD files (.fbx, .gltf, .3ds, .blend, .dxf, .glb, and more) and visualize them.
LiDAR Import: Upload LiDAR Point Cloud files (.laz) and visualize them anywhere within SiEGA.
Gaussian Splats: Upload Gaussian Splats files (.ply) to your project and visualize them using Unreal Engine's comprehensive Niagara system. NOTE: This feature is still in development, not all game features are guaranteed to work with Gaussian splats.
🔧 Improvements
Local 3D Tileset and Local Imagery save/load supported
CAD Import save/load supported
Media save/load supported
Datasmith save/load supported
Presenter save/load supported
All measurement tools save/load supported
🐞 Bug Fixes
Thumbnails are now correctly being deleted from user hard drive when the media itself is deleted
New User Interface would not get removed from the screen on logging out
Some User Interface elements were not consistent with the rest
🐛 Known Bugs
Selecting Gaussian Splats in select mode not working as intended
Selecting the walk mode character (Maria or Cooper) through the settings menu is broken at the moment
CAD Imported models are not saving their position correctly
Presenter arrow buttons are backwards (multiple assets loaded into single presenter)
Occasionally, thumbnails on media images are incorrect
Saving Datasmith and CAD imported models multiple times appears to not work
Fatal Error occasionally appears when exiting the application using the exit button in the actions menu

v2.0.0 - Initial Launch
Version 2.0.0 – [June 17, 2025]
Welcome to the official release of SiEGA! This is our first release note, so there isn't too much to say right now. But we'll give you some quick insight on what to expect for future releases! We will make an effort to ship out a new release each time a major improvement or feature is completed, as well as include smaller improvements, bug fixes, etc. as they are completed. During the SiEGA Viewer Preview Program, we had the most efficient development in the history of AERO AI and made frequent updates each month, so expect to see similar progress in the coming months! Here's a quick recap of what was available on release as well as some sneak peeks at future releases.
🚀 New Features
Selecting Mode: A quick way to enter a selecting mode where you can directly interact with assets.
Metadata Mode: Use your mouse pointer to hover over assets containing metadata to easily view the metadata of the object within SiEGA.

🐞 Bug Fixes
The entire Presets menu used to completely reset each time you closed and opened it. Now is persistent not only between opening and closing the menu, but can be saved and loaded using the save menu.
Resolved an issue where changing the weather while playing a video in the media tab would cause the user to get teleported a short distance away.
Fixed most occurrences where user can fall through the world into the dark abyss below while in walk mode.
Toned down the sensitivity of the fly mode panning and zooming, especially the closer the user gets to the earth.
🔮 Coming Soon
Viewshed: A tool that allows users to analyze visibility within a 3D environment by showing what areas are visible or obstructed from a specific point. When placed in the scene, the viewshed projects a visual cone indicating the line of sight, typically using color to distinguish visible and hidden areas. This is useful for applications like surveillance planning, camera placement, and understanding sightlines in urban or natural landscapes.
Presentor: A feature in SiEGA that allows users to upload and display images and videos directly within the 3D scene. This tool is designed for guided presentations, enabling content to be projected in the environment and viewed by others in real time. Whether showcasing site plans, visual references, or multimedia explanations, the Presenter feature enhances communication and storytelling within collaborative sessions by anchoring visual content to specific locations in the project space.
Virtual Reality Mode: A feature that offers an immersive way to explore and interact with your 3D environment using a VR headset. This mode allows users to experience scenes at a human scale, walk through environments, and engage with spatial data in a fully immersive setting.
