farm_prop

The built things on the farm — barns, silos, fence posts and rails, water tanks. One material for all of them: the mesh carries the colour per vertex and this shader hands it to the engine's own PBR lighting, so a corrugated silo and a tarred barn roof pick up the same low sun and cast the same long shadows as the crop. roughness_min/roughness_max ride the vertex alpha, which the mesh builder uses to make metal roofs read tighter than weathered timber.
