Refuse is the most-used and least-invested-in category of set dressing there is, which is why alleys in games so often repeat the same silhouette four times in a row. This is one of four distinct sacks built so that does not happen. Black, tied at the neck, with the knot modelled as real geometry — a knot faked in a normal map collapses the moment the camera passes it. The slump is weight-accurate: the bag sits down onto its own base the way a full sack does, rather than holding a balloon shape. The surface carries the fine stretch marks and tension creases thin polyethylene gets around a hard object inside it, and the shading keeps the material reading as film rather than rubber — a distinction invisible in a still and obvious in motion. 1,972 triangles, so a dozen in one street costs almost nothing.
