Untold Engine & Editor v0.24.0 Released!

[untoldengine]

This release brings major improvements to rendering on Apple Vision Pro, a redesigned asset workflow, new anti-aliasing options, and important stability fixes across the engine and editor.

Our focus continues to be making Untold Engine a reliable and accessible platform for building games and immersive experiences with Swift and Metal.

What's New in Untold Engine

Major Rendering Improvements for Apple Vision Pro

One of the biggest highlights of v0.24.0 is a significant overhaul of the headset rendering pipeline.

• Foveated Rendering — Better integration with visionOS compositor rasterization rate maps, improving rendering efficiency while keeping screen-space effects and occlusion culling correct.
• Temporal Anti-Aliasing (TAA) — TAA returns with improved temporal stability, motion-vector reprojection, and history filtering to help reduce shimmering and flickering.
• Forward Rendering — A new forward rendering path joins the existing deferred and hybrid options, giving developers more flexibility in choosing how their scenes are rendered.
• Improved Mixed-Reality Color — New color and tone-mapping options help virtual content blend more naturally with RealityKit and the surrounding environment.
• GPU Performance Metrics — Per-pass GPU timing provides better insight into rendering performance.

These improvements are particularly important for immersive applications, where image stability, performance, and visual consistency directly affect the experience.

Improved Project Organization

New projects now use a cleaner root-level directory structure:

• Resources/ — Source assets used during development.
• GameData/ — Cooked assets ready for use by the engine.
• Docs/ — Project documentation.

Existing projects remain supported and can be migrated using the new untoldengine convert command.

Reliability and Asset Improvements

We've also addressed several issues affecting everyday development:

• Fixed HDR environment restoration when loading scenes.
• Improved asset resolution for models and animations exported by the Editor.
• Removed unnecessary physics-component warnings during scene serialization.
• Corrected default height-map behavior to prevent unintended parallax effects.
• Added build-time warnings when Metal shader libraries are out of date.
• Moved starter asset downloads to GitHub Releases for more reliable installation.

What's New in Untold Editor

Redesigned Asset Browser and Import Workflow

The Asset Browser now works with the new Resources/GameData project structure.

Artists and developers can import source assets into Resources, organize them freely, and cook them into GameData when ready.

Highlights include:

• A new Import… button that automatically determines the appropriate destination.
• Right-click Cook to… actions for converting source assets.
• Separate Resources and GameData navigation in the sidebar.
• Breadcrumb navigation for easier asset organization.
• Improved empty-folder messaging and first-time workflow guidance.

This separation gives developers more control over their asset pipeline while keeping runtime-ready content organized.

New Rendering Controls

The Editor now exposes more of the engine's rendering capabilities directly through its interface.

• TAA and MSAA+TAA — New anti-aliasing options with adjustable history weight, clipping, and jitter settings.
• No Tone Mapping — A new None option for scenes that require a different color-management workflow, including mixed-reality experiences.
• Improved Height Detail Controls — Parallax and height-map settings are now grouped into a cleaner, more intuitive inspector section.

Stability and Usability Improvements

• More Reliable Play/Stop — Fixed a scene-restoration race condition that could cause missing-entity errors and intermittent environment-lighting issues.
• Code Components Naming — The former Plugins panel is now called Code Components, making the distinction between project-authored components and engine-level plugins clearer.
• Legacy Project Support — Existing projects continue to work without requiring an immediate migration.

Moving Forward

With v0.24.0, we're continuing to strengthen two important areas of Untold Engine: rendering quality and developer experience.

The Vision Pro rendering improvements help us build more stable and visually consistent immersive experiences, while the new asset workflow makes it easier to bring content from creation tools into the engine.

We're also continuing to invest in reliability, diagnostics, and tools that let developers spend more time creating and less time troubleshooting.

Our vision remains the same:

An engine that empowers creativity and never stands in its way.
