# hedge_leaf Clipped hedge foliage surface shader. World-space noise builds the read in three registers: a clump register drifts young-growth tint across the surface, a leaf register hashes per-leaf tint jitter and perturbs the normal so lighting breaks into facets, and a gap register sinks low spots toward interior_color for depth between leaf clusters. Wrap diffuse + sun shadow, a sparkle-masked blinn highlight, and a back-light transmission lobe (sss) that rims foliage against a low sun. flower_amt sprinkles blossom clusters; ao_amt darkens ground contact. Pairs with the preseed.hedge generator's geometry.
