Open Painter is a free, open-source 3D texturing studio inside Blender. Paint across 8 material channels, build non-destructive layers, and customise 50 editable smart materials. Add mesh-aware masks and procedural aging, bake mesh maps, and export for Unreal or Unity without switching apps. Core texturing works offline with no account. Optional AI turns material descriptions into editable layers, not just flat images.

Could you build this?
Partial The panel, layer, and smart-material UI can be vibe-coded as a Blender add-on, but real-time 3D painting, mesh-aware masking, and baking need solid graphics and Blender-internals knowledge that assistants often get wrong.
What it would actually take: Build as a Python add-on for Blender's API, with GPU shader code (GLSL) for live painting and a layer stack that composites in a non-destructive pipeline. The hard parts are fast projection painting onto UV space, mesh-aware masks like curvature and cavity, and baking maps (normal, AO, curvature) correctly across Blender versions. This needs a graphics or tools programmer who understands rendering, plus extensive testing across Blender releases.
