Workflow
Built for iteration, not ceremony
Whether you searched PBR generator, PBR maker, or image to PBR — the need is the same: a believable metal/rough baseline, then iterate without breaking exports.
Core metal/rough stack
Normal, roughness, metallic, AO, and height — the maps engines actually consume.
Map hub →Capture anywhere
Right-click web images (Chrome) or local files (Windows Explorer) — same PBR ZIP.
Capture →API when volume grows
Move from ad-hoc sessions to repeatable server-side generation in your pipeline.
PBR API →Browser PBR for production workflows
Convert image to PBR — normals, roughness, metallic, AO, height — on /generate. Share channel links like roughness map generator, create PBR materials, or grab free PBR textures from your own images.
Why GenPBR
Built for material iteration, not demo slides
A PBR texture generator for developers who need predictable maps they can ship—not black-box outputs that change every run.
Start generating freePrivacy
Client-side processing
Textures stay on your machine. No upload queue, no asset retention—suitable for unreleased game art and client work under NDA.
Preview
Live 3D material viewer
Validate grazing-angle response before export. Catch normal convention mismatches early instead of after engine import.
Export
Engine-ready output
PNG per channel, ZIP archives, or MaterialX. Drop into Unity, Unreal, Blender Principled BSDF, or Roblox SurfaceAppearance.
Iteration
Regenerate without penalty
Tune strength and re-run on the same base image. Paid plans keep adjustments free—you only spend credits on new source plates.
Capture
Right-click anywhere you find textures
Chrome Capture grabs webpage images; Windows Explorer Capture handles local files. Both download engine-ready map ZIPs with a few free uses per install.
GenPBR Capture →API
Pipeline automation
When manual uploads stop scaling, use the REST API for batch material generation in your build or asset pipeline.
PBR API →Fast workflow: image → PBR maps you can ship
Start from one texture (albedo / diffuse) and generate the core metal/rough set: normal, roughness, metallic (metalness), AO, and height. The goal is a coherent material—not a pile of unrelated filters.
- - New to the workflow? Start with image to PBR for the full “one plate → material” overview.
- - Need normals from a diffuse/albedo specifically? Use diffuse to normal map and validate the result in the viewer before export.
- - Want a focused page for a single channel? Open: normal map generator, roughness map generator, metallic map generator, height map generator, PBR materials, free PBR textures, or the texture map generator hub.
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.
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.
From the field
GenPBR cut my material iteration time from hours to minutes. The maps are predictable — I can re-export without surprises when art direction shifts.

}Why GenPBR is a practical PBR maker for teams
Generate PBR maps from images, validate them in 3D, and export in a way that fits real pipelines.
Client-side generation
Your browser can generate maps without requiring a separate desktop install. (Exact processing mode depends on the tool surface.)
Channel-by-channel iteration
Iterate roughness, metallic, normals, AO, and height so outputs stay coherent as a material.
Engine-friendly exports
Export formats and packaging are designed for real engine imports; confirm current options on the live tool and pricing page.
Bulk workflows
When you need multiple textures, use the bulk surface in the app rather than repeating single uploads.
API for automation
If your pipeline is code-first, the API is the right surface for repeatable jobs.
Capture extension & Windows shell
Right-click webpage images or Explorer files into a normal / metallic / roughness / AO ZIP — no upload dance.
Intent-specific docs
Use dedicated SEO pages for roughness/metallic/normal/height to keep onboarding links consistent.
Trusted by creators shipping real projects
If you found us via genpbr or gen pbr, the shortest path is still /generate. If you’re evaluating for a team, start with the hubs and comparisons linked above.
“GenPBR has revolutionized my workflow. I can generate professional PBR materials in seconds with stunning results.”
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, height map generator, free pbr, pbr materials, and image to pbr.
What is GenPBR Capture (Chrome & Windows)?
GenPBR Capture converts images to a PBR ZIP (normal, metallic, roughness, AO) from where you already work. The Chrome extension right-clicks webpage images; Windows Explorer Capture right-clicks local files. Both include free trial conversions, then optional plan API keys.
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 / height map maker). It is a free grayscale height map and free heightmap generator workflow—upload on /generate, tune height alongside normal and roughness, preview in 3D, and export PNG.
Where do I get free PBR / freepbr textures?
Generate them from your own images on free PBR textures or open /generate—no watermarks on core exports. GenPBR is a free PBR generator, not a third-party asset marketplace.
How do I create PBR materials or PBR maps?
Use the PBR materials page for materials-first intent, or the texture map generator hub for full PBR map sets. Both open the same /generate tool.
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.

FAQ
Straight answers
Workflow, privacy, and export — no filler.
What is GenPBR Capture?
GenPBR Capture turns images into a PBR map ZIP (normal, metallic, roughness, AO) from where you already work. Use the Chrome/Edge/Opera extension to right-click webpage images, or Windows Explorer Capture to right-click local files. Both share the same freemium Capture API — a few free conversions per install, then optional plan API keys.
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.
