Stefan3DAI's weekly 3D AI news breakdown covers: Tripo P2.0 Smart UV bringing automatic unwrapping with clean seams to the last stage 3D AI couldn't touch; Meshy 7.1 Ultra 4K hitting 4096³ geometry with up to 80 million triangles where stitches and engravings are real mesh, not texture paint; and GPT-6 Astra autonomously driving Blender and Unreal for modeling, rigging, animation, and walkable scenes. Also covers Hunyuan Miora, Hitem3D's new Agent, and four papers including one removing UVs entirely.
