Runtime graffiti system for Unity: spray, erase, save and load paint directly on walls or UV-mapped objects, with FPS demo and setup tools.Runtime Graffiti / Spray Paint System is a Unity asset for adding interactive spray painting to first-person games, sandbox projects, urban environments, and creative gameplay systems.The package lets players spray paint directly onto walls and UV-mapped objects during runtime. Paint is applied through mesh UV coordinates, so drawings appear on the actual surface instead of being placed as decals. Fast mouse movement is interpolated into continuous strokes, helping lines feel smooth instead of dotted.Included features:Runtime spray painting on paintable mesh surfacesRight mouse button eraserSave and load system for painted texturesAuto-save after painting or erasingFirst-person player controllerSpray can view modelSpray particle effectColor palette switchingDemo scene with paintable walls and propsMaterials, meshes, icons, and prefabsEditor builder for regenerating the demo setupEnglish documentation in TXT, MD, and PDF formatsThe system is customizable through Inspector fields such as brush radius, hardness, opacity, eraser size, paint range, texture resolution, save IDs, base colors, and selectable color palette.Suitable for graffiti games, urban exploration, sandbox tools, horror or stealth games with marking mechanics, multiplayer hangout prototypes, level annotation tools, and any project that needs runtime drawing on world objects.Unity 2022.3 LTS compatibleRuntime spray painting on UV-mapped mesh surfacesPaintableSurface component for walls, props, and custom meshesSprayPainter component with camera raycast paintingContinuous stroke interpolation to avoid dotted brush marksRight mouse button eraserSeparate spray and eraser radius, hardness, and opacity settingsRuntime Texture2D paintingPNG-based save/load systemAuto-save after painting or erasingManual save/load hotkeysStable Surface ID system for persistent drawingsFirst-person controller includedSpray can view model includedSpray mist particle prefab includedHUD/crosshair includedCustomizable color paletteDemo scene includedDemo meshes, materials, icons, and prefabs includedEditor builder for regenerating demo assetsDocumentation included in TXT, MD, and PDF formatsSupported OS:WindowsmacOSLinuxi'm use AI for Generate Photo
