This video demonstrates a local 3D AI texturing workflow that delivers sharp details, true albedo, runs on just 6GB VRAM, and is entirely free. The workflow uses Flux to Klein to project high-quality views onto a mesh from multiple camera angles.
Installation and Setup ⏱ 0:00
•Download the one-click install script from pixelminusartistry.com/textureprojectionworkflows•First set up Trellis 2 using the Trellis 2 installation guide•Download both the Trellis 2 GGUF script and Trellis 2 script from the Trellis 2 GGUF folder•Paste both into the ComfyUI Easy Install add-ons folder and execute them•Run the Trellis 2 GGUF model downloader.bat to download all needed models•Download the texture projection installer.bat from the same website and save it in the add-ons folder•Double-click the installer .bat file; it will handle custom nodes and dependencies•Launch ComfyUI (use ComfyUI.bat or ComfyUI flash attention.bat)•Drag and drop the workflow JSON files into ComfyUI; there should be no red nodes•Download required models using the markdown node links within the workflowSingle-Image Workflow Usage ⏱ 4:35
•Upload a single 2D image (e.g., a dwarf)•Set target face number (recommended 100k), texture resolution (1024 for 6GB VRAM), and character name•In the texture projection render conditions node, set resolution (e.g., 1024) and adjust flux subnets for side, back, front views•Adjust camera elevations and copy values to the texture projection bake textures node•Run the workflow; first launch may take time to download models and initialize•Result: a textured 3D model with normal map, with notably sharper details and fewer shadows compared to default Trellis 2 outputMulti-View Workflow for Better Accuracy ⏱ 10:10
•Open the texture projection multi-view workflow file•Upload multiple images (e.g., 4 views of a robot) to texture from all sides•Flux to Klein reads small details like rust and metalness from each view•Result is more accurate and detailed than single-image projection•Side-by-side in Blender: multi-view projection shows way more detail than default Trellis 2 textureRetexturing Existing Models and Fixing Issues in Blender ⏱ 11:43
•For existing GLB models, upload the model and paste the mesh path into the mesh input node•The workflow is faster (e.g., 119 seconds) and projects from each side•Note limitations: top and bottom may lack texture detail; adjust resolution to 4K for better quality•To fix projection issues in Blender: - Go to Texture Paint tab
- Use clone brush (select clone tool, Ctrl+click to copy area, paint over flaws)
- Save the image after painting (Image > Save)
•Workflow currently outputs only diffuse map; for roughness/metallic: - In shader editor, use a hue/saturation value node to desaturate base color → roughness
- Use a color ramp to create black/white metallic mask from base color
•Roughness and metallic Lora are being worked on by Error X and the communityKey Takeaways
•The workflow runs locally in ComfyUI on as little as 6GB VRAM and is entirely free.•It uses Flux to Klein to project high-quality views onto the mesh, generating true albedo without baked-in lighting.•Two versions exist: single-image and multi-view; multi-view provides more accurate texturing from all sides.•Existing GLB models can be retextured by providing the mesh path; the process is faster (e.g., 119 seconds).•Projection issues can be fixed in Blender using the clone brush in Texture Paint mode.Conclusion
This open-source workflow offers a major upgrade for local 3D texturing, with future improvements like roughness and metallic maps expected from the community.
