paving: https://polyhaven.com/a/gravel_concrete
Authors: Dario Barresi, Charlotte Baglioni
Physical tile: [2.12, 2.12] m
Pale mineral paving. Photographed fine aggregate, no baked joints.

rock: https://polyhaven.com/a/rock_boulder_dry
Authors: Dimitrios Savva, Rico Cilliers
Physical tile: [1.8, 1.8] m
Rough pale boulder; a visual limestone-like analogue, not a scan of local Perusic stone.

wood: https://polyhaven.com/a/oak_veneer_04
Authors: Jenelle van Heerden
Physical tile: [1.0, 1.0] m
Light natural wood grain with no baked plank joints. Existing geometry supplies vertical boards. Rotate UV by pi/2 for vertical grain.

soil: https://polyhaven.com/a/forest_ground_04
Authors: Rob Tuytel, Rico Cilliers
Physical tile: [3.15, 3.15] m
Mineral brown soil with scattered small stones.

The assets are visual material references, not surveyed or photographed evidence of this particular property. Original dimensions are publisher scan dimensions. No displacement of surveyed terrain is used.
JPEG recompression only; no colour grading or synthetic texture generation. All normals are OpenGL +Y. Color is sRGB; normal/roughness/AO are linear.

Revision 12: the driveway reuses the photographed gravel_concrete PBR set at the same 2.12 m tile coverage. Neutral grey tone applied in the material shader; normal, roughness and AO maps remain spatially aligned. This replaces the older procedural concrete texture on the approach.
