{"params":{"colorway":{"type":"choice","default":"granite-grey","label":"Colorway","describe":"Curated Nature & Forest stone schemes, all from the kit palette and all sharing the family used by this kit's large boulder and medium rock, so a scatter of mixed rocks stays coherent. granite-grey is the shipped mid warm-grey stone under bright spring moss; mossy-shade is a darker damp-forest grey under deep shade green, for the floor of a closed canopy; sandstone is a warm tan stone with dry yellow-green lichen, for sunlit clearings and riverbanks; dark-slate is a cold near-charcoal stone with very dark moss, for ravines and wet gullies. Sets stone, moss and lichen unless those are passed explicitly.","options":["granite-grey","mossy-shade","sandstone","dark-slate"]},"stone":{"type":"color","default":"#87847c","label":"Stone","describe":"Albedo of the rock body \u2014 every facet that is not a moss patch, about 85% of the visible surface and the dominant colour of the asset. A stone is one material, so this is its single flat tone at every size: all the value variation you see across the facets comes from their angles and the scene lights, never from this colour. Keep it a neutral mid rung of the kit grey ramp so the green reads."},"moss":{"type":"color","default":"#5f9a4b","label":"Moss","describe":"Albedo of the brightest green crust \u2014 the largest and best-turned of the patches, and the one colour block that has to be legible against the grey from 10 m, so keep it saturated and a clear value step off Stone. Unused when Moss cover is 0."},"lichen":{"type":"color","default":"#3d6b34","label":"Lichen","describe":"Albedo of the deeper green crusts \u2014 every patch except the largest one, roughly two thirds of the green on the shipped rock. Sits one clear value step below Moss; matched to Moss the patches flatten into a single sticker wrapped round the rim. Unused below a Moss cover of 0.15, where there is one patch only and it takes the Moss tone."},"size":{"type":"range","default":0.35,"label":"Size","describe":"Width of the stone across X in METRES. A genuine REBUILD, not a scale: the facet cell is a rock's repeat unit, so the number of cell BANDS wrapped round the stone follows its surface area (2 bands below 0.27 m, 3 at the 0.35 m default, 4 above 0.36 m) and each cell stays roughly a constant size in world units instead of the whole pebble getting coarser or finer. The crown gains a cell over the same range. 0.18 m is a stone you kick aside; 0.38 m is a chunky sitting rock. The range is skewed DOWNWARD on purpose: the store's variant proof frames the DEFAULT bounding box, and this pebble already fills it, so a top end much past +10% crops its own picture. Scenes wanting a bigger stone reach for the kit's medium rock.","affects":"geometry","min":0.18,"max":0.38,"step":0.01},"sides":{"type":"range","default":6,"label":"Sides","describe":"How many flat cells go round the plan \u2014 the knob that owns this rock's identity and the kit's \"5-8 sided\" style rule made explicit. 5 is a blunt wedge-cornered stone with long straight silhouette runs and wide creases; 6 is the shipped hexagonal pebble; 8 is a more eroded stone with shorter outline segments that still never curves. Changes the number of corners in every elevation and the triangle count; the 0.35 m footprint and the proportions do not move.","affects":"geometry","min":5,"max":8,"step":1},"squat":{"type":"range","default":0.62,"label":"Squatness","describe":"Height of the stone as a fraction of its width, so 0.62 is the shipped 0.216 m tall pebble under a 0.35 m footprint. 0.40 is a flat skimming stone that barely clears the grass; 0.74 is a chunky lump nearly as tall as it is deep. The cutting planes are re-solved against the new form, so the crown plateau and the shoulder band re-proportion and the cell layout changes with it \u2014 but a pebble has no repeating structure to multiply in height, so this rung rebuilds the cell pattern rather than gaining courses. The whole change is in the FRONT elevation.","affects":"geometry","min":0.4,"max":0.74,"step":0.02},"mossCover":{"type":"range","default":0.4,"label":"Moss cover","describe":"How much of the crown rim carries moss, as real crusts cut out of the stone's own cells \u2014 a bare stone margin, a 4 mm rim and a flat top \u2014 spread one per azimuth sector so at least one faces any camera. EXACTLY 0 is a clean bare stone with no green geometry and no green triangles at all, for dry, rocky or winter ground; 0.40 is the shipped rock, three patches about 0.09 m across; 1.00 wraps up to five slightly larger patches most of the way round the rim, a stone that has sat in deep shade for years.
