StableProjectorz is an open-source application that enables artists to texture 3D assets using Stable Diffusion on consumer NVIDIA GPUs, leveraging a novel multi-view conditioning scheme. By allowing artists to project diffusion-generated textures onto a 3D model while maintaining the original UV layout, the tool facilitates intuitive cross-view blending and inpainting directly on the model. The integration of 2D texturing and 3D mesh generation within a single interface enhances workflow efficiency, evidenced by a growing community of over 5,000 users since its release.
Artists can now seamlessly texture 3D models with AI-generated images while preserving intricate details and UV layouts, revolutionizing the asset creation process.
We present StableProjectorz, a free, open-source desktop application that lets a single artist texture a 3D asset by projecting Stable Diffusion generations onto its surface while preserving the original UV layout, on one consumer NVIDIA GPU. The central technical idea is a perspective-shifted multi-view conditioning scheme: up to six user-placed view arrangements are laid out in camera space through per-view projective offsets, their depth and view-space normals are composed into a single shared canvas that is fed to a ControlNet in the bundled WebUI, and the returned composite diffusion image is projected from every arrangement into a shared UV-space accumulation texture. Cross-view blending is resolved by the artist, painting per-view weight masks directly on the 3D model. Where regions need reworking, the artist paints color or colorless inpaint masks in UV space — these stay attached to the surface regardless of camera motion and are rendered to screen space only at generation time. A depth-aware projection mask then rejects pixels that would leak onto distant meshes in concave geometry; and UDIMs are supported natively via a geometry-shader-driven texture array. Two operating modes — 2D texturing via AUTOMATIC1111/Forge/ComfyUI, and integrated 3D mesh generation via bundled one-click installers for Trellis 1/2 and Hunyuan3D 2.0/2.1 — let the artist move between texture and geometry without leaving the tool. Initially released in January 2024 and open-sourced under AGPL-3.0 in January 2026, StableProjectorz has reached an estimated 105 installations and a community of more than 5,000 members.
