"instruction": "Procedural Wood Material `/home/user/Desktop/scene.blend` contains a 2x2 BU UV-unwrapped plane named `Board` at the origin. Launch Blender by running `blender` from a terminal. Use `/opt/blender/blender` for Blender command-line or background runs when working on `scene.blend`.\n\nIt has a grey Principled BSDF material `WoodMat` containing an Image Texture node referencing a blank 512x512 RGBA image datablock named `WoodBake`. The `WoodBake` image texture node is the active node on the material. Your task: rebuild `WoodMat`'s node tree into a procedural wood shader (NO external texture file — purely from shader nodes like Texture Coordinate, Noise, Wave, Vector Math, and Color Ramp), bake the diffuse color onto the `WoodBake` image, save the result to `/home/user/Desktop/wood.png` at 512x512, and save the completed scene to `/home/user/Desktop/answer.blend`. ## Requirements 1. `/home/user/Desktop/wood.png` exists. 2. `/home/user/Desktop/answer.blend` exists and preserves `Board`, `WoodMat`, a procedural node graph, and the active `WoodBake` image node used as the bake target. 3. Image is exactly 512x512. 4. Brown hue: mean R > mean G > mean B AND mean R in [0.2, 0.7]. 5. Banding detected: along the central row of the image, counting sign-crossings of (pixel luma - row mean luma), at least 4 zero-crossings (distinct bright/dark alternations). 6. Color variation: per-pixel luma standard deviation >= 0.05. 7. Dark and light present: min luma < 0.15 AND max luma > 0.40.",
