Design cinematic lighting by painting and placing sprites.Artists and developers can quickly create cinematic, stylized, or atmospheric lighting without complex lighting setups.Inspired by lighting design techniques used in visual development and concept art, LumiBrush brings a painting & sprite based workflow to lighting in Unity.How it works:You control where light appears by painting and positioning sprites.LumiBrush generates a dynamic light cookie for directional lights and spotlights.The system works in two main ways:Light SpritesLight Painting.Light Sprites:Light sprites can be moved, animated, or attached to objectsThey can use textures, colors and different blend modesMultiple sprites can be combined to build complex lighting shapesLighting updates in real timeLight Painting:A painting surface is created (plane or generated mesh based on scene topology)Brush strokes paint vertex colors on the meshYou can paint with different colors and intensity (Colors doesn't work for Butil in RP)These vertex colors are rendered to the dynamic light cookie textureLight Baking:Light baking can be done in Built in render pipeline and URP.Light baking doesn't support using different colorsNo support for light baing in HDRP right now.Performance:LumiBrush works by generating one dynamic light cookie texture for each light.Runtime cost consists mainly of:- A render pass that generates the cookie texture- Scene objects used for light sprites or paint meshes- No additional real-time lights are required.Lumibsurh is perfect for:Atmospheric environmentsStylized lightingCinematic storytellingRapid lighting iterationPrototyping scene mood and compositionWhether you are prototyping or polishing your final look, LumiBrush turns lighting into a fast, creative process instead of a technical chore.Paint and position light textures directly in the Scene ViewGenerate dynamic directional light cookies at runtimePaint lighting using vertex color brushesPlace light sprites and textures to shape lightingAnimate light sprites for moving light effectsAttach light elements to gameplay objectsSupports colored light and grayscale bake modesCompatible with Built-in Render Pipeline (doesn't support colors), URP, and HDRPIncludes editor tools, demo scenes, and setup utilitiesAI was used to assist with editor tooling, code generation and refactoring, + to improve product descriptions and documentation clarity.
