Cell Tiling Procedural - Substance Designer Tool (with Breakdown)

Cell Tiling is a powerful, highly customizable texture tiling generator built 100% inside a single Pixel Processor node in Substance 3D Designer.

It breaks away from standard grid tiling by using a procedural Voronoi cell structure to distribute your textures. This creates incredibly natural, organic patterns without visible repetition. Simply feed in a Height map (along with matching Diffuse, Roughness, or Normal maps), and the generator will organically distribute and blend your textures based on underlying height data.

Perfect for creating realistic stone pavements, organic ground cover, cracked soil, and stylized tile patterns.

Key Features
- 100% Pixel Processor Built: Optimized performance packed into a single node.
- Height-Based Blending: Tiles naturally adapt and blend using the input height data.
- Multi-Channel Support: Process Height, Diffuse, Roughness, and other maps simultaneously.
- Visual Debug Mode: Built-in visualization toggle to inspect your procedural masks instantly.

User Controls & Parameters
- Input Texture Scale: Easily adjust the scale of your source textures inside the cells.
- Auto Tiling (On/Off): Automatically scales and adapts cell sizes to match your input texture dimensions and avoid texture repetition inside the cell.
- Cell Size: Full control over the density and scale of the Voronoi cells.
- Irregularity: Shift between perfectly structured square grids and highly chaotic, organic cell layouts.
- Random Seed: Instantly randomize the offset, rotation, and distribution of the input textures.
- Blend Mode (Min/Max): Switch between blending methods to prioritize deep crevices or high peaks.
- Mask Expansion: Fine-tune the boundaries and thickness of the cell masks.
- Mask Blend Area: Smooth out or sharpen the transitions where the cells meet.

Performance & Limitations
- Tileable Inputs Required: Input textures must be tileable to ensure seamless distribution.
- Performance Cost: It is slightly more performance-expensive than the classic Cell Bombing method (which utilizes texture sampling).
- The Tradeoff: The minor performance cost grants significantly more customization options and completely avoids texture warping.
