<p><strong>Turns images into true PBR texture maps fast.</strong></p><p><strong>Who it's for:</strong> creators who want this pipeline in ComfyUI without assembling nodes from scratch. <strong>Not for:</strong> one-click results with zero tuning — you still choose inputs, prompts, and settings.</p><h3 id="open-preloaded-workflow-on-runcomfy">Open preloaded workflow on RunComfy</h3><p><a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/chord-model-workflow-in-comfyui-pbr-material-generation?utm_source=civitai&amp;utm_medium=referral">Open preloaded workflow on RunComfy (browser)</a></p><p><strong>Why RunComfy first</strong><br />- <strong>Fewer missing-node surprises</strong> — run the graph in a managed environment before you mirror it locally.<br />- <strong>Quick GPU tryout</strong> — useful if your local VRAM or install time is the bottleneck.<br />- <strong>Matches the published JSON</strong> — the zip follows the same runnable workflow you can open on RunComfy.</p><p><strong>When downloading for local ComfyUI makes sense</strong> — you want full control over models on disk, batch scripting, or offline runs.</p><p><strong>How to use (local ComfyUI)</strong><br />1.

Using Ubisoft's advanced rendering decomposition, it converts reference or generated textures into full SVBRDF maps. You can easily control output materials for real-time engines or VFX pipelines. Perfect for designers seeking high-fidelity detail and modularization. Achieve richer, more accurate textures with predictable, high-quality surface properties.</p><p><strong>Important nodes:</strong></p><h2 id="key-nodes-in-comfyui-chord-model-workflow">Key nodes in Comfyui CHORD Model workflow</h2><h3 id="cliptextencode-(4)"><code>CLIPTextEncode</code> (#4)</h3><p>Encodes your text into conditioning for the texture generator. Be explicit about material class, surface qualities, and tiling intent. Terms like orthographic, seamless, grout lines, pores, fibers, or micro-scratches help the generator produce structures that the CHORD Model can decompose reliably.</p><h3 id="ksampler-(7)"><code>KSampler</code> (#7)</h3><p>Drives the latent diffusion process that creates the texture. Use it to trade speed for fidelity, switch samplers, and explore variations via the seed. A blank negative prompt is provided by <code>ConditioningZeroOut</code> (#5); add typical negatives only if you see artifacts you want to suppress.</p><h3 id="modelsamplingauraflow-(2)"><code>ModelSamplingAuraFlow</code> (#2)</h3><p>Applies an AuraFlow-style scheduling to the UNet for sharper, coherent texture synthesis with z_image_turbo. Change the scheduler here when you experiment with different sampling behaviors packed with the model.</p><h3 id="chordmaterialestimation-(20)"><code>ChordMaterialEstimation</code> (#20)</h3><p>Runs the CHORD Model to estimate SVBRDF maps from the input texture. Results are production-ready base color, normal, roughness, and metalness. Use flat, evenly lit inputs without perspective to maximize accuracy; complex shadows or highlights can bias the decomposition.</p><h3 id="chordnormaltoheight-(18)"><code>ChordNormalToHeight</code> (#18)</h3><p>Converts the CHORD-predicted normal into a height map suited for displacement. Treat height as a relative surface signal and calibrate intensity in your renderer to match the intended scale.</p><h3 id="emptysd3latentimage-(6)"><code>EmptySD3LatentImage</code> (#6)</h3><p>Sets the canvas size and batch for texture synthesis. Choose a square resolution that matches your downstream material targets and keep this consistent across generations for predictable texel density.</p><h3 id="notes">Notes</h3><p><strong>CHORD Model Workflow in ComfyUI | PBR Material Generation</strong> — see <a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/chord-model-workflow-in-comfyui-pbr-material-generation?utm_source=civitai&amp;utm_medium=referral">RunComfy page</a> for the latest node requirements.</p>
