Most 3D AI tools force you to start from scratch every time you want to make a change.Anyone who’s used 3D AI has seen this: fix the hands, the toes break. Or you download a model and only need to tweak one part, not redo the entire asset.That’s the problem we’re trying to solve.We just launched an editing feature in our 3D AI tool, Rodin. It lets you edit existing 3D models by selecting an area and typing your prompt, without rebuilding everything.You can upload any model, or generate one from Rodin, and change only the part you want. For example: “Replace the head of this Gundam model with Crayon Shin-chan’s head.”This came from working with real production pipelines, where fast iteration matters more than one-shot perfection.Demo: https://youtu.be/-5_sSHeOmuc You can try it with this code for a 14-day Creator Plan: ME8EW4PMCRT4Happy to answer any questions.

Could you build this?
No Localized, generative 3D mesh inpainting and part-level mesh editing requires cutting-edge 3D computer vision and deep generative diffusion models.
What it would actually take: Requires training proprietary 3D generative diffusion models or Gaussian splatting/neural field architectures conditioned on 3D bounding boxes or mesh masks. The pipeline requires substantial GPU clusters, specialized expertise in 3D geometry processing (UV unwrapping, topology preservation, rigging compatibility), and high-throughput inference serving.
Discussion
2 comments analyzed.
Concerns raised: Fine-grained edits remain challenging, Cannot fully replace manual 3D modeling, Works better with clear regions than tiny details
