humanoid mannequin 3d model

A 1.8 meter tall scale reference mannequin for a Unity survival game asset workflow. The model is a simple humanoid blockout character used only for scale comparison, not a final game character. It should stand in a neutral upright pose with feet flat on the ground. The body is made from clean simplified geometric shapes: a rounded rectangular torso, simple block arms, simple block legs, simple feet, and a simplified head. The silhouette should clearly communicate human height and proportions without realistic anatomy. The mannequin should have accurate game scale proportions: total height 1.8 meters, eye height marker at 1.6 meters, shoulder width about 0.45 meters, body thickness about 0.25 meters, waist height around 1.0 meter, knee height around 0.5 meters. The model should include a visible horizontal eye-height marker line at 1.6 meters, preferably as a thin bright yellow or cyan bar crossing the upper body or floating beside the head. This marker is used to compare first-pers
