Early Access Software

Get involved with this software as it develops.

Note: This Early Access software is not complete and may or may not change further. If you are not excited to use this software in its current state, then you should wait to see if it progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Ra Engine is production-ready for the workflows it currently supports and is actively used
to develop Laser Tag and Launch Up. Early Access lets us ship a working, capable tool now
while continuing to build out the feature set — expanded Lua scripting, spot light cone
editor, GLB loading, and more — with direct input from the people using it day to day.”

Approximately how long will this software be in Early Access?

“6 to 12 months. Core rendering, editing, and Lua scripting are stable and in active
production use. The remaining work is depth, ergonomics, and expanding the toolset.”

How is the full version planned to differ from the Early Access version?

“The full release will add:

— Spot light cone editor with visual gizmos
— Full GLB loading support
— Expanded Lua scripting API
— Third-person camera system
— Denoiser for glossy reflections
— Additional documentation and example scenes
— Steam Workshop integration for Digiflux.one titles

The renderer and core editor are complete and shipping games today. What's coming is
depth and tooling.”

What is the current state of the Early Access version?

“Ra Engine currently includes:

— Full hardware Vulkan 1.4 ray tracing pipeline (reflections, refractions, emissive GI)
— ACES tonemapping and exponential depth fog
— Real-time scene editor: object hierarchy, groups, grab mode, material editing, fly mode
— GLTF 2.0 scene load/save with lights, materials, and custom extensions
— Point and spot light placement with physically calibrated attenuation
— Lua scripting system with hot reload, state persistence, and level progression
— Terminal-first UI with F-key menu system
— Three build targets: Ra Engine (editor), Digiflux runner (game), dev/validation

Actively used in production to develop Laser Tag and Launch Up. Stable on RTX 2060
class hardware.”

Will this software be priced differently during and after Early Access?

“Ra Engine is $49.99 per seat and will stay there. This is not an introductory price —
it is the permanent price. The goal is volume, not margin. One seat covers every
Digiflux.one title, current and future. Early adopters get the same deal as everyone else,
forever.”

How are you planning on involving the Community in your development process?

“Ra Engine development is driven by real production work on Laser Tag and Launch Up.
Developer and modder feedback directly shapes the tooling roadmap. We post development
updates, respond to the discussion board, and maintain a rolling roadmap of upcoming
features. If you hit a workflow gap, we want to hear about it.”

About This Software

Ra Engine is a hardware ray tracing scene editor and game engine built on Vulkan 1.4.
Every surface, shadow, and reflection is rendered with real RTX ray tracing — not baked,
not approximated — in real time as you build.

One seat unlocks level editing across the entire Digiflux.one game catalog.

Edit Every Digiflux.one Game


Every Digiflux.one game is fully editable in Ra Engine. Load any title, and the full
editor opens — scene hierarchy, material controls, lighting tools, fly mode, and Lua
scripting. Build a Laser Tag arena, hit play, run through it, adjust the lights, and
share it on Workshop.

Laser Tag — Build and edit custom arenas. Share on Steam Workshop.
Launch Up — Design and edit vertical platformer levels.
Every future Digiflux.one title — One seat. Level editing for every game, forever.

Key Features


  • Hardware RTX Ray Tracing — Full Vulkan 1.4 ray tracing pipeline. Reflections,
    refractions, global illumination, and emissive GI all in real time.
  • Level Editing for Every Digiflux.one Game — One seat unlocks the full editor
    for every title on the platform.
  • Terminal-First Editor — A developer-native workflow with no overlay UI. Navigate
    the scene hierarchy, adjust materials, place lights, and manage groups from a clean
    terminal interface with ANSI color.
  • GLTF 2.0 Scene Format — Open, portable scenes. Supports KHR_lights_punctual,
    KHR_materials_transmission, KHR_materials_ior, and custom Ra Engine extensions.
  • Theatrical Lighting Design — Inverse-square light attenuation, ACES tonemapping,
    emissive multi-sample GI, and tunable depth fog.
  • Scene Editor — Object hierarchy, group operations, grab mode, snap-to-ground,
    scale, material editing, and fly mode.
  • Lua Scripting — Hot-reloadable scripts, state persistence, level progression,
    and scale animations.
  • Built for Shipping — The engine behind Laser Tag and Launch Up on Steam.

Who Is Ra Engine For?


Laser Tag players who want to build their own arenas — Ra Engine is your editor.
Design maps with real RTX lighting and share them on Workshop.

Hobbyist developers who want hardware ray tracing without the overhead of a
general-purpose engine.

Studios who want a Vulkan-native RTX pipeline they can own and extend.
No licensing tiers. One seat per developer.
