On this machine, use `/opt/blender/blender` for Blender command-line or background runs when working on `scene.blend`.\n\nExport the whole scene to `/home/user/Desktop/output/scene.usda` as ASCII USD with the materials translated into USD `UsdPreviewSurface` shaders. ## Requirements 1. `/home/user/Desktop/output/scene.usda` exists and is readable. 2. The first line of the file starts with `#usda` (ASCII USD marker, not the binary `.usdc` header). 3. The file contains a `def Xform \"Cube_A\"` prim. 4. The file contains a `def Xform \"Cube_B\"` prim. 5. The file contains a `def Material \"Mat_A\"` block with a nested `def Shader \"...\"` definition. 6. The file contains a `def Material \"Mat_B\"` block with a nested `def Shader \"...\"` definition. 7. The token `info:id = \"UsdPreviewSurface\"` appears at least 2 times (once per material). 8. Inside the `Mat_A` block, `diffuseColor = (r, g, b)` has values close to (0.8, 0.2, 0.2) within +/- 0.05 per channel. 9. Inside the `Mat_B` block, `diffuseColor = (r, g, b)` has values close to (0.2, 0.8, 0.2) within +/- 0.05 per channel. 10. At least one `inputs:roughness = <float>` line is present (the scene's two Principled BSDF materials map their Roughness to this shader input).", |
