Tools for game development
C# and visual logic. Terrain, voxels and detailed 3D graphics. Your game’s tools, in one editor.
Core tools
All features
SharpGraph
Build gameplay visually. SharpGraph turns typed graphs into C#, with events, async actions and step-by-step debugging.
C# / .NET 10
Code beside your game. Semantic highlighting, Roslyn completion and C# refactoring inside the Reckfell editor.
Terrain
Give your world its shape. Sculpting, materials, vegetation and collisions in the integrated Terrain toolset with a C# API.
using var data = new VoxelBuffer();
data.Create(32, 32, 32);
data.SetVoxel(1, 16, 8, 16);Access chunk data from C#: read, edit and build geometry.
Voxel Tools
Build worlds in volume. Blocks, smooth terrain, caves and destruction with generation graphs, chunks and LOD.
Game-engine post-processing and color grading
Give every frame its character. Exposure, color, bloom and optics through camera profiles and local volumes.
Deferred
Detailed surfaces and clustered lighting. Deferred combines a G-buffer, shared materials and Forward passes for transparency.
C# and visual programming
C#/.NET 10, Roslyn completion and visual graphs that generate code. Build gameplay systems your way, within one project.
Explore
Materials, lighting and post-processing
Shape lighting, PBR materials and post-processing. Control exposure, color and optics through camera profiles and volumes.

2D / 3D / C#Code and graphs
A C# game engine with .NET 10
Build gameplay systems with C#/.NET 10. A typed API, integrated IDE and visual graphs work together in one project.
SharpGraph: visual C# scripting
Build gameplay visually. SharpGraph turns typed graphs into C#, with events, async actions and step-by-step debugging.
A built-in C# IDE for game development
Code beside your game. Semantic highlighting, Roslyn completion and C# refactoring inside the Reckfell editor.
Games and worlds
A built-in terrain editor for 3D games
Give your world its shape. Sculpting, materials, vegetation and collisions in the integrated Terrain toolset with a C# API.
Voxel tools for editable worlds
Build worlds in volume. Blocks, smooth terrain, caves and destruction with generation graphs, chunks and LOD.
An engine for making 2D games
Platformers, puzzles and dialogue-driven stories. A 2D editor, physics, animation, UI and gameplay in C# or SharpGraph.
An engine for making 3D games
Create detailed 3D worlds. Entities and prefabs, Terrain and Voxel Tools, PBR materials, lighting and post-processing.
Graphics
Game-engine post-processing and color grading
Give every frame its character. Exposure, color, bloom and optics through camera profiles and local volumes.
Deferred rendering for 3D games
Detailed surfaces and clustered lighting. Deferred combines a G-buffer, shared materials and Forward passes for transparency.
Shader Graph and custom effects
Go beyond material presets. Visual graphs, text shaders and access to frame data.
ExperimentalReckfell Radiant: experimental GI
Experimental global illumination with world probes, software tracing and color transfer. Available in a separate test build.
Workflow
Entities, levels and prefabs
Build levels from reusable parts. Entities define the hierarchy, .rscene stores a level and .rprefab stores an object template.
Level editing and workspaces
A workspace for the task at hand. Code, graphs, resources and your game in tabs, with floating panels and saved layouts.
Game-editor automation with MCP
Connect AI to editor tools through MCP. Local models and external OpenAI-compatible providers can work with your project.
