wwii helmet 3d model

Generate one WWII Imperial Japanese Army pith helmet as a game-ready 3D model. It should have a rounded, segmented dome, a gently flared brim, light olive-khaki woven fabric, visible stitched seams, and a narrow sewn fabric band around the crown. Add a small yellow five-pointed star on a matching pentagonal cloth patch at the front. Include a hollow underside with a thin shell and cloth lining. Maintain consistent proportions from the front, back, sides, top, and underside. No straps, buckles, head, mannequin, or stand. Target approximately 1,000 triangles total with clean topology, smooth shading, and efficient UVs. Use high-quality PBR materials with 2K base-color, normal, roughness, and ambient-occlusion maps. Keep the fabric matte and nonmetallic. Bake stitching and fabric texture into the maps while preserving the rounded silhouette and defined brim. Avoid strong shadows or lighting baked into the base color.
