Fix Mesh and Rig AI 3D Models in Blender

Learn to transform AI-generated character concepts into fully rigged 3D models ready for animation and game development through a complete production pipeline. Master the process of generating clean multi-view reference images from AI concepts, converting 2D artwork to detailed 3D meshes using Hitem3D, and preparing characters for animation in Blender. Discover how to fix common scale and positioning issues with automated Python scripts, optimize high-density meshes while preserving detail, and create professional character rigs using Blender's Rigify system. Explore techniques for generating front, back, and side reference views, exporting FBX files, cleaning up imported geometry, and binding meshes to armatures with automatic weights for seamless animation workflows suitable for game development, prototyping, and character variations.
