Yedp123 Debuts ComfyUI-Yedp-UV-Painter For Easy 3D Texturing
ComfyUI-Yedp-UV-Painter is an experimental, non-destructive 3D-to-2D AI texturing node for ComfyUI. It bridges professional 3D pipelines with AI image generation directly inside the browser interface. Users can surgically texture complex multi-mesh 3D models using an SDXL stack on a modest 8GB VRAM GPU.
Developer Yedp123 who also made other powerful custom nodes such as ComfyUI-Yedp-Mocap, created this custom node to enable layer-based workflows with strict memory management. They built the system to treat AI texturing like Photoshop layers for independent generation. The project also includes an automated regional prompting tool to pair text prompts with the correct UV geometry masks.
Project features and technical capabilities
Key Features
- Non-destructive generation stack for layered texturing.
- Live 3D Canny preview for drawing details.
- Accurate multi-mesh support for isolated UVs.
- Automated regional prompting with geometry masks.
- Optimized for 8GB VRAM consumer graphics cards.
3D artists and indie game developers can use this tool to quickly apply detailed textures to their models. Small studios working with limited hardware will appreciate the ability to generate game-ready assets without high-end equipment. Anyone needing precise control over specific material zones on complex meshes will find the layer system useful.
Developer notes and current limitations
The developer notes that this lab-built tool is currently in its V1 MVP stage. One known limitation is that UDIMs are not supported because the system relies on standard 0-1 UV coordinate space. Additionally, extremely tiny or fragmented UV islands might be ignored by the AI due to SDXL VAE compression blocks.
"Areas of the 3D mesh that have not yet been assigned a generation layer will display as a solid gray base-coat in the final composite." - Source: GitHub
