Only 12 nodes. No spaghetti wires. Just load your model, write your prompt, and hit generate.<hr /><h3 id="important-nodes-2.0-required">⚠️ IMPORTANT — Nodes 2.0 Required</h3>This workflow is built for the Nodes 2.0 (Vue) interface of ComfyUI. If you don't enable it, the workflow may have display problems.How to activate Nodes 2.0:<ol><li>Open ComfyUI</li><li>Go to Settings (⚙️ icon, bottom-left)</li><li>Find "Use Nodes V2 (Vue)" and toggle it ON</li><li>Refresh the page</li><li>Load the workflow</li></ol>If you prefer the classic interface, check out my Legacy version of this workflow instead (<a target="_blank" rel="ugc" href="https://civarchive.com/models/1309324/wan21txt-to-video">link</a>).<hr /><h2 id="features">🎯 Features</h2><ul><li>Text-to-Image generation</li><li>Automatic download of models in auto version</li><li>Built-in SeedVR2 upscaler — high-quality tiled upscaling (toggleable on/off) Slower than a classic upscaler, but significantly better quality</li><li>Full metadata embedding — your images are saved with all generation parameters, ready for online publishing and remixing</li><li>3 LoRA slots — with individual on/off toggles and strength control and you can connect as many other lora modules to each other for as many LoRA as you want.</li></ul><hr /><h2 id="custom-node-required">📦 Custom Node Required</h2>Only one custom node to install:👉 <a target="_blank" rel="ugc" href="https://gitlab.com/UmeAiRT-Studio/ComfyUI-UmeAiRT-Toolkit">ComfyUI-UmeAiRT-Toolkit</a>Install via ComfyUI Manager (search "UmeAiRT") or use the UmeAiRT Auto-Installer.
