Texture Splatting & Bombing Toolkit

Procedural Material Generation The Texture Splatting & Bombing Toolkit is a free, Editor-only utility designed to procedurally combine, blend, and modify textures directly within Unity. Rather than relying on external image editors to create material variations or scatter details, this suite allows you to bake multiple input textures into a single, flattened PBR texture set using GPU-accelerated algorithms. Whether you are blending dirt and rock for a static environment mesh, stamping debris across a ground texture, or simply reorganizing RGBA data maps, this toolkit provides a fast, offline pipeline for generating new texture assets from your existing library. Tool 1: The Procedural Compositor (Splatting & Bombing) The core feature of this suite is the Texture Combiner. It allows you to assign up to four distinct texture sets and procedurally fuse them into a new material using two distinct GPU-accelerated assembly methods. - Texture Splatting (Noise Blending): The tool generates a master splat map using configurable fractal (fBm) or cellular noise. It then mathematically cross-fades the assigned texture layers based on your defined dominance, sharpness, and scaling parameters. - Texture Bombing (Cloning): Designed for scatter details, this mode takes a smaller input texture, such as leaves, pebbles, or debris, and stamps it across a designated background canvas. The algorithm applies randomized rotation, scale, and distribution density to break up repeating patterns and create an organic spread. - Automated Aspect Fill: If you assign input textures of varying resolutions or dimensions, the engine safely center-crops them to perfectly match your target output bounds without destructive stretching. - Presets & Detached Previews: Save your exact procedural configurations as ScriptableObject presets, and visualize your composite materials in a detached, dockable 2D GPU preview window before saving them to disk. Tool 2: The Seamless Sandbox This utility takes raw, non-tiling images and mathematically processes them to tile seamlessly. It provides two distinct algorithmic strategies to handle different types of input. The mirroring method uses symmetry combined with noise disruption to break up obvious kaleidoscope effects, while the offset method centers the seams and applies an fBm cross-mask to blend them away. The sandbox processes all assigned PBR maps (Albedo, Normal, Mask, Height) synchronously using the exact same offsets and noise seeds, ensuring perfect alignment across the entire material set. Like the Combiner, this module natively supports automated Aspect Fill for irregularly sized inputs and features its own detached GPU preview window for visualization. Tool 3: The Batch Channel Packer A dedicated utility for reorganizing and optimizing texture data. It allows you to take separate grayscale maps—such as ambient occlusion, roughness, and metallic maps—and swizzle them into a single packed data texture, like a standard Unity Mask Map. The packer includes a batch-processing mode, enabling you to apply the exact same extraction and inversion rules to an entire folder of textures simultaneously. Unlike the Combiner and Seamless Sandbox, the Channel Packer acts as a rigid 1:1 pixel data translation tool. To protect the integrity of your material coordinates, it does not use Aspect Fill and will explicitly block generation if it detects mismatched aspect ratios among your inputs. Limitations & Scope To ensure this tool fits your specific use case, please note its practical limitations: - Input-dependent quality: This toolkit will not magically generate normal maps or mask maps from scratch, nor will it make a poor-quality texture look good. The quality of the final generated asset is strictly dependent on the quality of the input textures provided. It only blends, bombs, and swizzles existing data. - Inherent seamless artifacts: Algorithmic seamless generation inherently introduces visual artifacts or texture warpin
