Patina：图片生材质

Patina: Image to Material

用 Patina 把一张表面照片变成可无缝平铺的 PBR 材质。原图定下花纹，Patina 把它重绘成可平铺的材质，同时返回 basecolor、normal、roughness、metalness、height 五张图，彼此逐像素对齐。适合砖、石、木、灰泥、织物、瓷砖等表面；也可以加蒙版，只重绘图片的一部分。

300 "# Patina Material\n\n**Photo -> complete, seamlessly tiling PBR material.** The source image sets the pattern; Patina redraws it as a\ntiling material and returns basecolor / normal / roughness / metalness / height maps from the same latent, so the whole\nset lines up pixel for pixel. Partner (API) node: it runs on Comfy's servers, needs an account, nothing renders locally.\n\n## Input Asset\n\n- [patina_brick_wall.jpg](https://raw.githubusercontent.com/Comfy-Org/workflow_templates/refs/heads/main/input/patina_brick_wall.jpg)\n\n## How to use it\n\n- **Load Image** holds the surface photo. Anything with a regular structure works: brick, stone, wood, plaster, fabric, tile.\n- `prompt` describes the material you want back, not the scene. Name the pattern and the finish, and add\n \"flat even lighting, no perspective\" - that is what makes the result tile.\n- `strength` (advanced, 0.6 here) sets how far it moves away from the photo: low keeps the original texture, high\n rewrites more of it.\n- The optional **mask** input inpaints a region (white = regenerate, black = keep). A mask without an image raises an error.\n- Want a texture from text alone, with no source photo? Use the Patina Material text-to-material template instead.\n Want the maps of a photo without making it tile? The Patina PBR Maps node is the direct converter.\n\n## Outputs - wire in this slot order\n\n`0 texture` . `1 basecolor` . `2 normal` . `3 roughness` . `4 metalness` . `5 height` . `6 expanded_prompt`\n\nEvery map can be switched off, but at least one has to stay on. Fewer maps = a cheaper, faster run.\n\n## Tips that actually matter\n\n- `image_size`: presets 1024², 512², 4:3, 3:4, 16:9, 9:16, or `custom` (512-2048, step 16).\n- `num_inference_steps` tops out at 8 - there is nothing to gain above that.\n- `tile_size` is in latent space: 128 is about 1024 px, 64 about 512 px. `tiling_mode` = both / horizontal / vertical.\n- `prompt_expansion` is **off by default on purpose**: the LLM rewrite reframes the prompt as a photo and tends to wash\n out the metalness map.\n- `upscale_factor` 2 or 4 upscales the **maps only** (SeedVR) - the base texture is never upscaled.\n- Structured materials work best. Free-form marble, flat gradients and anything relying on readable text come back as\n plausible-looking nonsense.\n\n## This workflow\n\nBrick wall photo, basecolor and normal maps on. Every save node writes to `patina/<yyyymmdd>-<hhmm>_<map>`, so one run's\nfiles sit next to each other in the output folder and runs from different days never mix."
