SpriteIlluminator is a dedicated normal map editor developed by CodeAndWeb that allows game developers to add 3D dynamic lighting effects to flat 2D sprites. By creating a normal map, the software gives 2D game objects volume, depth, and realistic texture shadows when a light source moves around them. Core Workflow in SpriteIlluminator
The general workflow for a standard tutorial follows these steps:
Importing Assets: Drag and drop your 2D sprite images or sprite sheets into the left panel of the interface. Generating the Base Normal Map:
Bevel Tool: Automatically uses the transparency data of your sprite to inflate the surface, creating instant rounded corners and volumetric 3D shapes.
Emboss Tool: Uses the color and brightness variations of your flat art to raise or lower specific sections of the surface. Manual Fine-Tuning:
Use Selection Tools (like color selection) to isolate specific parts of the asset, such as treating a character’s arm separately from their chest.
Apply specialized brushes like the HeightBrush or AngleBrush to paint precise contours, tilts, and creases directly onto the map.
Adding Textures: Use the StructureBrush to overlay material patterns like reptile scales, fur, chain mail, or cracked stone without modifying your original artwork.
Real-Time Light Testing: Click and drag the virtual light icon across the preview window to test how your sprite reacts to custom light colors, overexposed brightness, and Z-axis depth changes.
Exporting: Click Publish to output your completed normal map, which saves automatically with a _n suffix alongside your original image asset. Engine Integration Examples
Once your normal map is generated, it must be paired with your base sprite inside your game engine:
