nring_meadow

Procedural Eifel meadow for the Nürburgring terrain and verges: lush and sun-dried grass drifts, yellow-green patches, tussock clumps, a fine blade grain and bare soil on steep cuts, all in world space so the 20 km terrain needs no UVs. Octaves fade with pixel footprint (no shimmer on distant hills). Vertex colour marks worn verges (1-r = soil) and mown strips (1-g). Used by the nring_grass material.
