How this service works

Texture tools: PBR maps from one albedo image: normal (OpenGL for Unity/three.js and DirectX for Unreal), 16-bit height, roughness and ambient occlusion, plus a lit preview. Full schema: https://rengi.dev/v1/texture-tools/schema

Output

Returns a set of PBR map images derived from the input albedo: an OpenGL normal map (for Unity/three.js), a DirectX normal map (for Unreal Engine), a 16-bit height map, a roughness map, an ambient occlusion map, and a lit composite preview image.

Example use cases

Unity indie game texture setup

“I have a wood plank diffuse texture at https://cdn.mygame.com/wood_diffuse.jpg — can you generate all the PBR maps for Unity? I want OpenGL normal format, normal strength around 2.5, and let the system figure out roughness automatically.”

Unreal Engine environment art pipeline

“Generate PBR maps from my brick albedo image (base64 attached) for Unreal Engine — I need the DirectX normal map, height map, roughness, and AO. The grout between bricks is light-colored and raised, so please invert the height.”

three.js web scene material creation

“I'm building a three.js scene and need a complete PBR material from this concrete texture URL: https://assets.mysite.com/concrete.png — give me the OpenGL normal map with strength 4, roughness around 0.8, and a lit preview so I can check how it looks.”

When to prefer

Choose this endpoint when you need a complete PBR map set (normal in both OpenGL and DirectX conventions, height, roughness, AO) generated automatically from a single albedo texture — ideal for game developers targeting Unity, Unreal Engine, or three.js who want to skip manual authoring in Substance Painter or similar tools. Prefer this over generic image-processing APIs when you need game-engine-ready outputs with correct normal map conventions per engine.

Side effects

Invalid or undecodable base64 image data — returns 400 error
Image URL unreachable or returns non-image content — returns 400 or 422 error
Image format not PNG, JPEG, or WebP — returns 422 validation error
roughness value outside 0–1 range — returns 422 validation error
normalStrength outside 0.1–10 range — returns 422 validation error
Payment not provided or insufficient (x402 protocol) — returns 402 Payment Required
Image too large or processing timeout — returns 500 or 504 error
