Choosing between tools? Use /compare to compare workflow, licensing, and what you actually get on export.

Common pitfalls (quick checks)

  • - Masks in the wrong color space: metallic/roughness/AO/height should be treated as linear in most engines.
  • - Channel packing mismatch: confirm ORM expectations before export.
  • - Normals convention: DirectX vs OpenGL green channel differences still bite teams.
  • - Iteration scope: check whether regenerating one channel invalidates sibling maps in your pipeline.
Open /generatePricing

Predictable results for professional PBR texture generation

In production, you want the material to behave the same way every time you regenerate it. That means you can iterate quickly, compare changes, and keep exports consistent across a team.

Why repeatability matters

  • - Version control friendly: stable outputs make reviews and regressions easier.
  • - Tunable parameters: you can iterate roughness/metallic/normal strength intentionally.
  • - Fast iteration: adjust, preview, regenerate, export—without rebuilding your pipeline docs.

Where to start (fast)

The quickest path is the live generator on /generate. If you want a one-page explainer you can share, use image to PBR.

Export without rework

Most “bad results” are actually import issues: wrong color space, wrong channel packing, or a naming mismatch. Use this quick handoff checklist before you commit assets or ship a build.

1) Color space

Masks are usually linear. If roughness/metallic/AO/height get imported as sRGB, the material will look wrong even if the pixels are fine.

2) Packing + conventions

If you pack ORM (or similar), verify the target expects the same channel order. For normals, confirm your engine’s green-channel convention (DirectX vs OpenGL).

3) Naming

Keep suffixes consistent so tools can auto-match maps. One stable convention beats “smart guesses” every time in a team pipeline.

FAQ: PBR generators, maps, and exports

Quick answers to common searches like normal map generator, pbr generator, image to pbr, roughness map generator, and metalness map generator.

Is there a free normal map generator online?
Yes. Use the normal map generator page (normal map maker / creator) or open /generate—upload diffuse or albedo, preview in 3D, export PNG. No signup for core resolutions.
How do I make PBR textures from an image?
Upload on /generate or follow image to PBR. GenPBR generates normal, roughness, metallic, AO, and height together—the texture map generator hub covers the full PBR texture creation workflow.
Is there a free height map generator online?
Yes. GenPBR includes a dedicated height map generator (also searched as heightmap generator). Upload on /generate, tune height alongside normal and roughness, preview in 3D, and export PNG.
What is a texture map generator?
A texture map generator creates the full PBR stack—normal, roughness, metallic, AO, and height—from one source image. Use the texture map generator hub for the complete workflow, or jump to individual channels like normal or roughness.
How do I convert an image to PBR?
Upload your albedo or photo on /generate or follow the image to PBR guide. GenPBR generates normal, roughness, metallic, AO, and height maps together so the material reads coherently under lighting.
What is a PBR texture generator?
A PBR texture generator creates a set of physically-based maps (usually normal, roughness, metallic/metalness, AO, and height) that your engine uses to shade a material under lighting. The important part is generating a coherent set that exports cleanly—so the same material read holds up in-game.
How do I generate a PBR texture from an image?
Start with a base-color/albedo (often called diffuse), generate the metal/rough maps, then validate the material read together (roughness + metallic + normal) before you export. For the full flow, see image to PBR.
Do you support roughness and metalness map generation?
Yes. Use the dedicated tools for roughness map generator and metallic / metalness map generator, or generate a full set from the texture map generator hub.
Why does my roughness/metallic export look wrong in-engine?
Most issues are import settings: masks should typically be treated as linear (not sRGB), and some pipelines expect a specific channel packing order (like ORM). Also confirm normal conventions (DirectX vs OpenGL).

Automation when you outgrow one-off uploads

If your intent is “PBR converter” or “batch texture generation,” you probably need a pipeline surface. GenPBR offers an API surface for teams that want predictable integrations.

Frequently Asked Questions

Quick answers about the GenPBR PBR texture generator workflow.

Why is algorithm-based PBR generation better than AI/ML tools like DeepBump?
Algorithm-based PBR generation provides 100% predictable and consistent results - the same input always produces identical output, which is critical for production pipelines and version control. Unlike AI tools like DeepBump that use unpredictable neural networks, our mathematical algorithms offer complete control, instant client-side processing with no server uploads, work offline, have zero rate limits, and deliver transparent results without 'black box' AI guesswork. Professional game developers and 3D artists prefer this reliability for Unity, Unreal Engine, Blender, and Maya workflows.
What is physically based rendering (PBR)?
Physically based rendering is a shading and rendering technique that simulates how light interacts with real-world materials. Our PBR generator creates the essential maps (normal, metallic, roughness, ambient occlusion) needed for realistic 3D materials in games, films, and architectural visualization.
What PBR maps does GenPBR generate?
GenPBR generates five essential PBR maps: Normal maps for surface detail, Metallic maps for material properties, Roughness maps for surface irregularities, Ambient Occlusion maps for realistic shadowing, and Height maps for displacement mapping. These maps work together to create photorealistic 3D materials. You can export all maps individually, as ZIP archives, or in MaterialX format.
Is my data secure with client-side processing?
Yes! All texture processing happens locally in your browser. Your images never leave your device, ensuring complete privacy and security. This also means faster processing since there's no server upload/download time.
What file formats are supported?
GenPBR supports common image formats including PNG, JPG, and WebP for input. Generated PBR maps are exported as PNG files with transparency support. You can export materials in multiple formats: individual PNG files, organized ZIP archives containing all maps, or complete MaterialX (.mtlx) format for industry-standard material definitions. All formats are compatible with major 3D software including Blender, Maya, 3ds Max, and game engines like Unity and Unreal Engine.
How does the 3D viewer help with material creation?
Our real-time 3D WebGL viewer lets you preview your PBR materials on different 3D shapes with adjustable lighting. This instant feedback helps you fine-tune your textures and see exactly how they'll look in your final 3D scenes or games.
