Use any piece on its own.

The engine itself. Components, scenes, rendering, physics and audio, in one ordinary .NET library your game references directly.

A low-level GPU abstraction over Vulkan and Direct3D 11, with macOS via MoltenVK. Powers the rendering layer.

Model importing for glTF 2.0, GLB, VRM, OBJ and FBX into one read-only model graph. Pure C#, no native dependencies.

Serialization via an intermediate representation you can inspect and modify before it becomes binary or text.

The immediate-mode UI framework the editor is built in. Retained-mode results, immediate-mode ergonomics.

Turns any triangle mesh into a non-overlapping UV atlas, ready for lightmaps and AO bakes.

Image decoding in managed C#, replacing the ImageMagick dependency for texture loading.

Hardware-accelerated, anti-aliased 2D vector graphics. The renderer underneath Paper.

TrueType parsing, text layout and Markdown, with no native dependencies. Draws the text Quill renders.

Vectors, matrices, geometry, noise and collision, in 32- and 64-bit. The math the others are built on.

A .NET wrapper over the Slang shader compiler, covering its COM API plus shader reflection and type APIs.

A tiny, high-performance tokenizer that lexes directly over a ReadOnlySpan<char>. Built for DSLs, markup and config formats.

The official component library for Paper. The widgets and gizmos the editor interface is assembled from.

Script hot-reloading. Components opt into reload behaviour with IReloadAware and ReloadIgnore.

A progressive CPU lightmap baker. Path-traced direct and indirect lighting, BVH4 and AVX2 accelerated.

Lightweight, backend-agnostic localization for .NET. Works outside Prowl just as well as inside it.

A pure .NET 2D physics engine. Rigid bodies, collision shapes and constraints, with no native binaries.

Authoritative client-server multiplayer with IL-weaved RPCs and automatic state replication. No source generators.
