I developed an automated 3D apparel animation pipeline that transforms custom T-shirt designs into professional social media content in under 5 minutes. Using Daz 3D's Genesis 9 avatar, I created a realistic walk cycle, then simulated and tailored the garment in Marvelous Designer with precise physics settings to prevent clipping. In Blender, I built an efficient rendering system with pre-configured lighting, materials, and camera rigs that automatically adapt to different designs while maintaining consistent quality. The pipeline handles complete asset integration - from OBJ geometry to Alembic animations and UV textures - enabling quick swaps of colors, patterns, and graphics without manual reconfiguration. Future development will expand the system to female avatars and other items of clothing.
