Texture RePainter is a tool that empowers artists and developers to edit, enhance, and customize textures directly within the Unity Editor.Texture RePainter is a powerful Unity editor tool designed to streamline the process of texture editing. Built with flexibility and efficiency in mind, this tool empowers artists, developers, and indie creators to refine textures without relying on external image editors—saving time and maintaining creative control within the Unity Editor.Whether you're working on 2D or 3D games, Texture RePainter integrates seamlessly into your workflow with a rich set of tools that support both precision-based painting and procedural generation. From detailed brush work to advanced color correction and filter effects, this package offers everything needed to polish your game assets and elevate the visual quality of your project.DocumentationKey Use Cases:Texture Painting & Editing: Paint directly onto textures using customizable brushes, erasers, and advanced blending modes (Blend, Replace, Tint, Additive, Multiply).Color Adjustments: Fine-tune the look of your textures with intuitive HSL (Hue, Saturation, Lightness) sliders for color grading.Filter Effects: Apply grayscale, invert colors, brightness/contrast adjustments, sepia tones, Gaussian blur, posterize, and oil painting filters—all within Unity.Procedural Pattern Generation: Generate clean, repeatable patterns like checkerboards, hexagons, waves, polar grids, tartan, and more for use in backgrounds, UI elements, or material design.PBR Map Creation: Create and edit Physically Based Rendering (PBR) maps including Albedo, Normal, Height, Metallic, Smoothness, Occlusion, and Emission maps with adjustable intensity settings.Texture Library Management: Import, store, and manage multiple source and brush textures for easy access during editing sessions.Texture Preview System: Zoomable and scrollable preview window with grid overlay, original vs edited comparison toggle, and cursor indicator for precise editing.Export Options: Save edited textures in PNG or JPG formats with adjustable resolution scaling and optional compression settings. Exported textures can also be added directly to your Unity project library for immediate use.Customization & Flexibility:Texture RePainter supports full customization of brushes, including size, opacity, rotation, and alpha ignoring for fine-tuned control over every stroke. It also allows users to import custom brush textures for unique artistic styles. The interface is highly modular, with collapsible panels, tabbed navigation, and a searchable tool menu to help keep your workspace organized.The tool works well across all major art styles—from pixel-perfect retro visuals to hyper-realistic environments—and is especially useful for teams or solo developers who want to iterate quickly on texture assets without leaving the Unity Editor.Ideal For:Indie developers looking to reduce reliance on third-party toolsPixel artists needing precise control over texture detailsEnvironment artists creating seamless tiling textures or pattern overlaysUI designers generating clean, scalable icons or background graphicsAnyone wanting to enhance their Unity workflow with in-editor texture refinementWith undo/redo functionality, responsive UI, and extensible scripting APIs, Texture RePainter is not just a utility—it’s a complete texture editing solution built right into Unity.Texture RePainter is a fully-featured Unity editor tool that enables in-editor texture editing with a wide range of tools and customization options. Built using Unity’s Editor scripting API, it leverages Texture2D, RenderTexture, and Unity UI components to deliver high-performance editing capabilities directly within the Unity Editor environment.Core Features:1.
