Gaussian Splat + FLUX.2 Klein: A ComfyUI Workflow for Precise AI Furniture Staging
TBG______ · reddit · 2026-09-11
A developer shares an in-progress ComfyUI workflow for architectural virtual staging using 3D Gaussian Splatting:
- Pipeline: furniture image → native TripoSplat (Image to Gaussian Splat) node → custom 3D compositing test node (auto-loads background, sets size, loads model) → three reference images fed to FLUX.2 Klein Edit.
- Reference design: background image, 3D mask combined with the furniture (indicating position/rotation), and the original material image.
- Prompting: treat the 3D placement as a guide — the model must correct perspective, lighting, scale, and soft shadows for photorealistic integration; full prompt included.
- Status: the official splat preview node lacks image output and Load 3D can't open splat files yet; a native 3D compositing node has been requested. Test node is open-source on GitHub; full tutorial coming soon. MinMax H3 was tested as a Klein alternative but wasn't consistently better.
