New 3D AI Tools: Meta's Mesh Flow & Claude's Spatial Leap

Summary

Meta AI has released Mesh Flow, a free and fast retopology tool that generates artist-like meshes in one second from input images, existing meshes, or point clouds. While initial tests show mixed results, it represents progress in simplifying retopology. Cloud's Fable 5, despite a temporary suspension due to government action, demonstrates significantly improved spatial reasoning, outperforming GPT 5.1 5 and enabling better understanding of 3D spaces for tasks like game development. Tripo AI now offers 8K texture generation, with Roden pushing to 12K for highly detailed applications. Nvidia's Artefixer enhances 3D reconstruction by cleaning up Gaussian splats, and World Labs has published research on single-image 3D reconstruction, merging depth and 3D understanding, and 4D Gaussian splats for video production. Cozy Blanket Pro is a promising new tool for cleaning up 3D meshes on Windows, rebuilding the existing iPad app from scratch. Lastly, Hyper 3D now supports splitting models for 3D printing, complete with connectors and watertight meshes, making it easier to print 3D models from 2D images.
