Raxicore Editor

A cross-platform desktop viewer, editor, and unpacker for engine-derived game assets, written in C# / .NET 10 with an offscreen-Vulkan 3D viewport.

---

Raxicore Editor opens the container formats the engine ships next to its client executable — archives, meshes, animations, textures, surfaces, and the ASCII databases — and renders, inspects, and edits them. The asset-format code is an original C# reimplementation of the container and content formats used by an engine-derived client.

You need your own copy of the engine-derived game assets. No game data is included or distributed with this project.

Features

• Asset browser — mount a folder or open an archive; a role-grouped catalog (Continents, Models, Animations, Textures, Surfaces, Databases, Audio) alongside the raw on-disk tree. Archive contents load lazily.
• 3D viewport — Silk.NET Vulkan rendered fully offscreen (no swapchain) and shown in Avalonia via a WriteableBitmap, sidestepping windowed-surface / device-loss crashes.
• Textured models — decodes .ubr UberMesh geometry and resolves each material to its DDS texture from the sibling dds_*.fat archives, with a per-material texture picker and one-click NC / TR / VS empire swap so vehicles aren't stuck on a single skin.
• Animation — plays skeletal (skinned) and rigid mesh-on-bone animations; anims.ubr auto-loads from the asset folder and clips are filtered to those that actually drive the selected model.
• Continents — opens a mapNN.ubr as a full continent: terrain tiles placed and textured, plus the static scene objects (bases, towers, trees, warpgates) resolved from contents_mapNN.mpo and the shared uber.ubr object library.
• Format tools — DDS/image preview, a paintable .srf surface-type editor, game_objects and generic ASCII-database table views, live-validated text editing, and a hex fallback.
• Export — write the active document's bytes, or export a mesh to Wavefront OBJ (+ MTL + textures).

Supported formats

Format	Extension(s)	Read	Notes

ASCII database	.adb	✅	chunky / asciidatabase, incl. game_objects
Surface tile	.srf	✅	128×128 surface-type grid (paintable)
Map manifest	contents_mapNN.mpo	✅	tile / object placement
DDS texture	.dds	✅	BC1/2/3 + uncompressed 32-bpp
LZO1X	—	✅	the PACK codec

Requirements

• The .NET 10 SDK
• A Vulkan-capable GPU (for the 3D viewport)
• Windows or Linux

Build & run

dotnet build RaxicoreEditor.slnx -c Debug
dotnet run --project src/RaxicoreEditor.Editor

Then File → Open Folder… and point it at your engine-derived game's install directory.

RaxicoreEditor.EngineAssets is a standalone, UI-free library (PACK, FLAT, UberMesh, UberAnim, ADB, surface, MPO, DDS, LZO1X) reusable for headless tooling. The editor references it.

Tech

UI is Avalonia 12 with the ShadUI theme (follows the OS light/dark setting). The 3D viewport uses Silk.NET Vulkan bindings, rendered offscreen. All dependencies are permissively licensed (MIT / Apache-2.0 / OFL) — see THIRD-PARTY-NOTICES.md.

Status

A functional viewer/editor: browsing, 3D rendering, texture selection, animation playback, and continent assembly all work. Per-format re-pack (write-back) beyond the surface editor and OBJ export is the in-progress edge.
