<h1 id="pixal3d-trellis.2-native-tuning-workflow-nearly-official-comfyui-nodes">Pixal3D / TRELLIS.2 Native Tuning Workflow — nearly Official ComfyUI Nodes</h1>nearly Official ComfyUI NodesA tuning and comparison variant of ComfyUI's official native Pixal3D &amp; TRELLIS.2 image-to-3D workflow. It exposes separate CFG, steps and seeds for both models, plus FOV override, Shape Upscale bypass, remesh controls, PBR map previews and GLB export—without requiring a third-party generation node pack.ComfyUI公式ネイティブ版Pixal3D／TRELLIS.2フローを、比較・調整向けに再構成したワークフローです。両モデル別のCFG・Steps・Seedに加え、FOV、Shape Upscale迂回、Remesh、PBR Map確認、GLB保存を操作できます。サードパーティ製生成ノードは不要です。<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/72542f70-4296-4208-bd52-1d2530f9356d/original=true/72542f70-4296-4208-bd52-1d2530f9356d.jpeg" /><img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/1c5eb6ad-b8e8-4531-9f68-62cbbc98b561/original=true/1c5eb6ad-b8e8-4531-9f68-62cbbc98b561.jpeg" /><h3 id="what-this-is">What this is</h3>This is an experimental parameter-surfaced variant of ComfyUI's official Pixal3D &amp; TRELLIS.2: Image to Model template.The official graph already provides a complete native image-to-3D pipeline. This version does not replace its models or inference implementation. Instead, it reorganizes the graph into a practical tuning lab so that Pixal3D and TRELLIS.2 can keep separate settings and be compared from the same input.This workflow is best understood as a middle layer between:<ol><li>using the official template as a mostly fixed reference graph; and</li><li>installing a large third-party 3D node pack for deeper experimental features.</li></ol>ComfyUI公式の Pixal3D &amp; TRELLIS.2: Image to Model をベースに、モデル比較と調整のための操作UIを追加した実験用ワークフローです。モデルや推論処理を独自実装へ置き換えたものではありません。公式ネイティブパイプラインを保ったまま、グラフ内に散らばっていた値をPixal3D用・TRELLIS.2用・共通設定へ分け、同じ入力画像から両者を比較しやすくしています。位置づけとしては、次の中間です。<ol><li>公式テンプレートをほぼ固定状態で使う</li><li>大規模なサードパーティ製3Dノードパックを導入して拡張する</li></ol>公式ノードだけで、調整可能性を一段増やすことを目的にしています。<h3 id="what-is-exposed">What is exposed</h3><ul><li>Three dedicated control groups: shared, Pixal3D, and TRELLIS.2</li><li>Per-model routing for Structure, Shape, Upsample, and Texture CFG/steps</li><li>Centralized Structure, Shape, and Texture seed controls</li><li>Manual FOV override, with <code>0.0</code> retaining the official MoGe-estimated path</li><li>Shape Upscale bypass routed to both Texture Stage and shape decoding</li><li>Per-model Remesh Smooth Iterations and Project Back values</li><li>Central controls for target face count and decimation placement mode</li><li>Externalized Normal Map Cage Distance at exact value <code>0.02</code></li><li>Five additional <code>Render Mesh → Preview Image</code> checkpoints: sparse mesh, decoded shape, painted decoded shape, post-processed mesh, and vertex-color mesh</li><li>The incompatible Advanced 3D Preview/Save nodes are retained but bypassed; active preview/export uses <code>Render Mesh → Preview Image</code> and standard <code>Save GLB</code></li></ul><ul><li>共通／Pixal3D／TRELLIS.2の3つの操作グループ</li><li>Structure／Shape／Upsample／TextureのCFG・Stepsをモデル別に切り替える配線</li><li>Structure／Shape／Texture Seedの中央集約</li><li><code>0.0</code>で公式のMoGe推定経路へ戻る手動FOV Override</li><li>Texture StageとShape Decodeの両方へ反映されるShape Upscale迂回</li><li>モデル別Remesh Smooth Iterations／Project Back</li><li>Target Face Count／Decimate Placement Modeの中央操作</li><li>Normal Map Cage Distance <code>0.02</code>の外部入力化</li><li>Sparse Mesh、Decoded Shape、Painted Decoded Shape、Post-processed Mesh、Vertex-color Meshの5地点に<code>Render Mesh → Preview Image</code>を追加</li><li>動作しないAdvanced 3D Preview／Saveは残したままBypassし、実行経路を<code>Render Mesh → Preview Image</code>と通常版<code>Save GLB</code>へ置換</li></ul><img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/0c03430a-7563-4b39-a12c-f8db8317bbd7/original=true/0c03430a-7563-4b39-a12c-f8db8317bbd7.jpeg" /><h3 id="important-implementation-details">Important implementation details</h3><ul><li>Texture Resolution is 4096 intentionally.
