# Edit 3D models with AI prompts | Rodin Gen-2 Edit Source: https://www.youtube.com/watch?v=KUiyOKHXoaE Recap page: https://rapidrecap.app/video/KUiyOKHXoaE Generated: 2026-02-02T08:33:15.935+00:00 --- ## Quick Overview The video demonstrates the Rodin Gen-2 Edit feature in the HYPER3D platform, showcasing advanced AI-powered local modification of 3D models using prompts, including examples of changing clothing details like pants and jackets, and successfully generating new geometry based on these edits, which are then shown to be compatible with external software like Cinema 4D. **Key Points:** - The demonstration focuses on Rodin Gen-2 Edit, a feature allowing users to modify existing 3D assets using AI prompts on specific regions. - The initial model used for editing is a stylized character described as "Boy with headphones holding coffee" (0:07). - The user successfully modifies the character's pants from the initial style to "orange cargo pants" using the Local Modify feature (0:08-0:10, 2:51-3:05). - A second modification changes the character's green sweater to a "denim jacket over a white shirt" (3:41-3:46). - The demonstration also covers breaking down the model into smaller parts using the "Bang to Parts" feature (4:55-5:20), resulting in separated components like the head, body, and accessories. - After generating the final material version, the model is imported into Cinema 4D (6:21), confirming the geometry and material package compatibility with external 3D software. - The platform charges 0.5 credits for the geometry refinement process when using the "Bang to Parts" feature (5:27). ![Screenshot at 0:08: The user initiates a local modification on the 3D model of the boy by drawing a selection box around the lower body and inputs the prompt "Change denim jacket over a white shirt" to alter the clothing geometry.](https://ss.rapidrecap.app/screens/KUiyOKHXoaE/00-00-08.jpg) **Context:** The video showcases the capabilities of Rodin Gen-2 Edit, the next-generation foundation model from HYPER3D, which is designed for detailed, prompt-based editing of existing 3D meshes. This new iteration allows for precise local modifications, object decomposition ('Bang to Parts'), and material refinement, aiming to streamline the creation of production-ready 3D assets directly from initial generations or imported files. ## Detailed Analysis The video tutorial focuses entirely on demonstrating the new 'Edit' feature of the Rodin Gen-2 AI foundation model within the HYPER3D platform. The session begins by loading a base 3D character model, "Boy with headphones holding coffee" (0:07). The key feature highlighted is 'Local Modify' (or Partial Redo), which allows users to select a specific region of the 3D model using a bounding box and apply a text prompt to alter only that area's geometry. The demonstrator first changes the character's yellow/orange shorts to "orange cargo pants" (2:51-3:05) and subsequently changes the top garment to a "denim jacket over a white shirt" (3:41-3:46), showcasing the precision of the localized editing. Following geometry edits, the video demonstrates the 'Bang to Parts' feature (4:55), which automatically separates the complex model into its constituent components (head, body, cup, etc.) for further refinement, costing 0.5 credits (5:27). Finally, after confirming the material generation, the resulting 3D model (now fully textured, as seen from 5:52 onwards) is exported and imported into Cinema 4D (6:21), proving that the generated assets maintain high quality and compatibility with industry-standard 3D software. ### Geometry Editing Workflow - Initial model ("Boy with headphones holding coffee") loaded - User selects 'Local Modify' using a bounding box - Edits clothing details via text prompts like changing pants to "orange cargo pants" and sweater to "denim jacket over a white shirt" - Edits are confirmed, initiating generation (0:07-3:46). ### Part Decomposition - Demonstrates the 'Bang to Parts' feature, which breaks the model into individual floating components for granular control (4:55) - This process costs 0.5 credits (5:27) - The resulting parts are shown separated in the viewport (5:11). ### Material Generation and Finalization - After geometry modifications, the user generates new materials based on the initial image prompt (5:36) - Multiple material iterations are shown before confirming the final look (5:52-6:04) - The final high-definition model is ready for download (6:19). ### External Software Integration - The final, textured asset package (including .obj file and textures) is imported into Cinema 4D (6:21) - The imported model appears correctly structured, confirming seamless workflow integration (6:27-6:45). ![Screenshot at 0:05: The initial user interface of HYPER3D showing the 3D editor with a character model undergoing modification via prompt input.](https://ss.rapidrecap.app/screens/KUiyOKHXoaE/00-00-05.jpg) ![Screenshot at 0:22: A slide highlighting the core capabilities of Rodin Gen-2 Edit, including 3D Editing, Third-Party Import, and Base 3D Generation.](https://ss.rapidrecap.app/screens/KUiyOKHXoaE/00-00-22.jpg) ![Screenshot at 0:38: Demonstration of the 'Local Modify' feature where a bounding box is drawn around the SUV's front section to input a prompt for style change.](https://ss.rapidrecap.app/screens/KUiyOKHXoaE/00-00-38.jpg) ![Screenshot at 3:46: The result of editing the character's top, showing the prompt "Change denim jacket over a white shirt" successfully applied to the selected area of the model.](https://ss.rapidrecap.app/screens/KUiyOKHXoaE/00-03-46.jpg) ![Screenshot at 6:26: The exported 3D model imported into Cinema 4D, displaying the model's geometry in the 3D viewport, ready for texturing.](https://ss.rapidrecap.app/screens/KUiyOKHXoaE/00-06-26.jpg)
