Modly brings AI 3D model generation to the PC: free, open source, and completely offline
A desktop alternative to cloud services for generating three-dimensional meshes via artificial intelligence is here. The open source project makes it possible to transform images and text into 3D models using only the local GPU.
Most AI 3D model generators work through cloud platforms. The user uploads an image, the remote server processes it, and returns the result. Modly, developed by Lightning Pixel, proposes a radically different approach: bringing the entire process onto the user's computer.
The application allows you to generate three-dimensional meshes from images or text prompts. It works completely offline once the program and necessary models are installed. It requires no credits or subscriptions.
- Open source software with MIT license for local 3D model generation
- Completely offline processing via local GPU
- Support for multiple open source AI models (TripoSG, Trellis2, Hunyuan3D 2 Mini)
- Compatible with Blender, Unity, Unreal Engine, and 3D printing
A unified environment for open source AI models
Modly does not introduce a new proprietary generative model. Its value lies in accessibility: it makes several open source AI models usable without complex configurations.
The project works as a desktop environment that eliminates the need to manually configure Python environments, CUDA dependencies, and different repositories. The user can install extensions to integrate models such as TripoSG, Trellis2, and Hunyuan3D 2 Mini.
The source code is distributed under the MIT license. It can be modified, integrated into other projects, or adapted to specific workflows in compliance with the license terms.
Simplified workflow: from image to mesh
The generation process requires just a few steps. The user provides a visual or textual input, selects the AI model, and starts local processing.
The workflow accepts images in PNG, JPG, or WebP format, or textual descriptions. After choosing one of the installed AI models, processing is performed by the local GPU. The resulting three-dimensional model appears directly in the Modly interface.
The results can be exported to modeling software such as Blender, graphics engines such as Unity or Unreal Engine, or prepared for 3D printing.
The process is not equivalent to a metrological three-dimensional scan. With a single photograph, the AI only knows what is visible in the image and must estimate the geometry of the non-visible parts.
Hardware requirements and compatibility
Local execution requires adequate hardware. The system supports NVIDIA GPUs with the CUDA toolchain and Apple Silicon processors.
Modly uses the GPU for processing generative models. NVIDIA GPUs with CUDA dependencies and Apple Silicon architectures are supported. Compatibility with macOS is confirmed.
The extension system allows integrating new AI models as they are made available by the open source community. The workflow system allows chaining generation processes for more complex operations.
Implications for additive manufacturing
The availability of local tools for AI generation of 3D models reduces the barriers to entry for rapid prototyping and customization.
The offline approach eliminates privacy issues related to sending images to external services. For industrial applications that require design confidentiality, this feature represents a significant advantage.
The ability to quickly generate meshes from photographs or textual descriptions accelerates the initial phases of concept design. The resulting models can be refined in traditional CAD software before 3D printing.
The absence of per-generation costs makes rapid iteration on design variants economically sustainable. This translates into shorter development cycles for prototypes and custom components.
The publicly available source code allows companies to integrate the technology into proprietary pipelines. The MIT license offers flexibility for specific adaptations without restrictive license constraints.
