Summary: This study examines how well stature scaled 3D human models made in Blender using the Human Generator add on match measured human anthropometry for forensic biomechanics applications. Eight dimensions, including stature, reach distances, limb lengths, and span, were compared between participants and their corresponding virtual models, with error summarized using MAPE and MPE plus bootstrap confidence intervals. Agreement was excellent for stature and strong for several segment and reach measures, often within about 5 percent. The study also identifies specific areas where accuracy can be improved, particularly arm span underestimation and a tendency to overestimate lower leg length in males. Overall, the findings support the practical usefulness of stature scaled 3D models while providing clear guidance on measurements that may benefit from additional verification.
