KvasA 3D game engine in Rust

A Unity-style editor, node-based materials, hot-reloaded Rust scripts and one renderer for the editor and the shipped game.

Quick start

Scripting

Materials and nodes

🧩

Node editor

190 nodes - noise with previews, Color Ramp, normal and height maps, light, angles, faces, glow. Materials, object shaders and camera effects.

🎨

326 built-in materials

Realistic and stylized procedural materials in every new project - stone, metal, wood, fabric, lava, toon, galaxy, holographic foil.

🦀

Rust scripts, made easy

One `script!` block declares variables for the Inspector and the callbacks. Helpers for movement, hierarchy, tags, shared variables, vertices and UVs.

🛠️

Mesh tools

Deform vertices from scripts - wave, twist, bend, noise - plus planar, cylindrical and spherical UV projection and crease-angle smoothing.

🔊

Directional sound

Spatial audio with a cone angle - a loudspeaker that is quieter behind and to the sides - and gizmos that show it in the scene.

📚

Documentation that stays true

Script examples are compiled and run by the test-suite, the node reference and the material catalogue are generated from the code.
