What it solves

StableGen is a Blender addon that simplifies the creation and texturing of 3D assets by integrating generative AI. It eliminates the need to switch between external AI tools and 3D software, allowing users to generate textured 3D meshes from images or text and refine textures on existing models directly within the Blender viewport.

How it works

The addon uses a ComfyUI backend to connect Blender to several AI models. It leverages TRELLIS.2 for generating 3D meshes from single images or text prompts. For texturing and refinement, it utilizes diffusion models like SDXL, FLUX.1-dev, and Qwen Image Edit. The system employs a multi-view consistency approach, using cameras to project textures onto the mesh from various angles, with advanced blending and inpainting to ensure seamless transitions. It also includes a specialized 3D printing suite that converts textured meshes into multi-color formats using physical color mixing theory.

Who it’s for

It is designed for 3D artists, concept artists, and game developers who want to accelerate their asset creation pipeline, as well as 3D printing enthusiasts who need to export AI-generated textures to multi-color slicers.

Highlights

• Image/Text to 3D: Generates fully textured meshes using TRELLIS.2 with multiple resolution modes.
• Scene-Wide Texturing: Applies textures to all mesh objects in a scene simultaneously for a cohesive look.
• Advanced Camera Control: Offers seven placement strategies and auto-aspect ratio framing to optimize texture projection.
• Precision Refinement: Features a Local Edit Mode for targeted texture modifications and UV Inpaint for filling gaps.
• 3D Print Export: Exports to 3MF/STL with a physical color mixing solver to prevent pigment bleed and banding.
• ControlNet & IPAdapter Integration: Uses depth, canny, and normal maps to maintain geometric accuracy and reference images for style guidance.
