Lightning Engine

Lightning Engine is a 3D game engine and editor built from scratch. It ships with a feature-rich desktop editor for authoring scenes, materials, assets and more.

It's in active beta. Everything listed below works today; what's next is on the roadmap further down.

Rendering

• Physically based rendering (PBR) with metallic & roughness components
• Image-based lighting (IBL) with diffuse and specular prefiltering
• HDRI skyboxes and ambient reflection
• Normal mapping with tangent space (MikkTSPace)
• Directional, point and spot lights
• Light culling optimized to support 64k+ lights at 60fps on mid-range hardware
• DirectX 12 renderer; Vulkan is in progress

Editor

• Scene management - create, rename, enable/disable entities
• Entity Component System (ECS): Transform, Script, Geometry
• Renderer viewport (multiple viewports supported)
• Visual Studi integration (with MSBuild)
• Developer console & change history
• Drag-and-drop FBX import for static meshes
• Texture import with BC block compression and texture grouping
• Geometry & texture inspector
  

Which download do I need?

• Lightning-Setup.exe - recommended. Installs the engine and every dependency for you.
• Lightning-Installer.msi - if you already have Visual Studio or the VS Build Tools installed
• lightning-engine-v?.?.?.zip - manual install, for people who like to do it themeselves

If Lightning Engine is useful to you, or you just enjoy watching an engine grow in the open, a tip goes straight into more development. No pressure either way.

Lightning Engine follows  Game Engine Programming Series closely.
