PATINA

What PATINA is

PATINA is fal.ai’s material-generation model for creating tiling PBR textures from text or image inputs. Text prompts can produce complete materials that upscale to 8K, with basecolor, normal, roughness, metalness, and height maps available. For image-based work, an image URL can be used to make texture variations; an image and mask can instead regenerate white regions while retaining black regions. The endpoint offers tiling in both directions, horizontally, or vertically, and lets you configure tile size and stride. Requests can produce 1–4 texture images and use 1–8 denoising steps. Exports are available as PNG, JPEG, and WebP, and the model listing permits commercial use. The paid service is available through web and API access. Its PATINA material inference plan is billed per request: $0.01 base, plus $0.02 per megapixel and $0.01 per megapixel per map type. Upscaling adds $0.004 or $0.016 per pre-upscaling megapixel per map for 2x or 4x, respectively. fal also offers a related endpoint that extracts material from a photo, flattens it, makes it seamless, and predicts PBR maps.

Who it suits

PATINA suits artists and developers who need tiling materials and PBR maps generated from prompts or image references. Its API examples and commercial-use designation are relevant to teams incorporating generated materials into software or commercial workflows.

Limits

Each request supports 1–4 texture images and 1–8 denoising steps. Inference costs $0.01 base plus $0.02 per megapixel and $0.01 per megapixel per map type; 2x and 4x upscaling add $0.004 and $0.016 per pre-upscaling megapixel per map, respectively.

Getting started

1. Open the PATINA material page on fal.ai.
2. Choose web or API access.
3. For API use, follow the JavaScript, Python, or cURL example and authenticate with FAL_KEY.
4. Submit a text prompt or provide an image URL; for inpainting, provide an image and mask.
5. Set tiling options and request 1–4 texture images with 1–8 denoising steps.
6. Choose available maps and export as PNG, JPEG, or WebP.

Verdict

Choose PATINA if your workflow needs text- or image-driven tiling textures, PBR maps, and resolution up to 8K. Its API examples and commercial-use designation may suit integration and commercial production. Look elsewhere if the per-request and per-map charges do not fit your workflow.
