Creating Tileable Textures and Texture Atlases for Games
Tileable materials and texture atlases directly impact game performance. We create seamless textures and optimize draw calls with over 8 years of experience, having completed more than 50 projects for PC, consoles, and mobile platforms. No Photoshop painting: we work in Substance Designer and Unreal Engine 5, using script-based texture packing via TexturePacker. The result is a reduction in draw calls by up to 70% compared to individual textures, saving thousands in rendering costs. Contact us for a free project estimate.
Why tileable textures deserve special attention?
A tileable texture is not just a seamless image. If it has a distinct repeating element, a tiling artifact appears that kills immersion. We solve it with three methods:
-
Stochastic tiling in the shader — multiple samples with UV variation and blending. In Unreal Engine 5, the node
World Aligned Blend; in Unity ShaderGraph, a custom HLSL block. Overhead is minimal, texture memory stays unchanged. - Multi-layer approach — an overlay texture with a different tiling scale is applied over the base. Different UV scales create an illusion of uniqueness.
- Virtual Texturing — for huge terrains, each tile gets a set of details, but requires powerful GPU.
According to Unity documentation, proper atlas usage can reduce draw calls by 70% for static scenes. An atlas reduces draw calls by a factor of 3.3 compared to individual textures — a significant GPU resource saving. This makes texture atlases 3.3 times more efficient than using unique textures per object.
How a proper PBR texture is created?
For serious production, we use Substance Designer: a parametric graph where the texture is an algorithm. A typical tileable material graph includes:
- Shape generator — base form.
- Noise and Warp — edge variation.
- Height to Normal — conversion via Sobel filter.
- Level and Curve — calibration to PBR values.
The final set includes five maps: Albedo, Normal Map, Roughness, Metallic/AO, Height Map. Height Map is critical for Parallax Occlusion Mapping or Tessellation. Procedural textures in Substance Designer are 5 times faster to produce than hand-painted alternatives.
Texture Atlas: how to pack without quality loss?
An atlas reduces draw calls: instead of ten materials, one material with one texture. Keeping texel density consistent is crucial: a small prop on a 256x256 atlas on a 2048x2048 texture gets 8 times poorer resolution. Assets are distributed by area: hero props get more space, background props less.
Tools: TexturePacker, Unity Sprite Atlas for 2D, Unreal native Texture Atlas Generator. Rules: minimum 2–4 pixel padding, atlas dimensions are powers of two for correct mipmapping.
Typical mistakes and how we avoid them
- Normal Map with incorrect Tangent Space. Symptom: dark bands along seams. Solution: we explicitly specify Tangent Space on export (DirectX for Unreal, OpenGL for Unity).
- Albedo with baked lighting. Shadows or AO in a tileable texture are fatal. We export clean Albedo.
- Atlas without mip-map consideration. A 4096x4096 texture with hundreds of small sprites on mobile gives blurry patches. We check all mip levels.
Scope of work
Each project includes:
- Source .sbs graphs (on request)
- Ready map set (minimum 5) in required formats
- Optimally packed atlas
- Artifact check in the target environment
- Integration consultation
The following tables summarize typical timeframes and quality comparisons.
| Task scale | Estimated timeframe |
|---|---|
| Single tileable texture (Substance Designer graph) | 2–4 days |
| Tileable texture set for a biome (5–10 materials) | 1.5–3 weeks |
| Texture atlas for a prop set (up to 30 objects) | 3–5 days |
| Texture atlas for a 2D project (UI + sprites) | 1–2 weeks |
| Criterion | Manual painting in Photoshop | Our approach (Substance Designer + optimization) |
|---|---|---|
| Repeatability | Patterns often visible | Stochastic tiling, multi-layer — pattern broken |
| Edit flexibility | Redraw from scratch | One parameter in the graph |
| Performance | Draw calls not optimized | Atlas + batching — draw call reduction up to 70% |
Our approach pays off through draw call reduction — you get up to 70% rendering savings, which can save approximately $5,000 per project. Pricing is determined individually after analyzing the requirements. We'll evaluate your project free of charge — get a consultation right now.
