The secret sauce is the Two-Prompt System: separation of powers between your base generation and the final refinement.⚠️ IMPORTANT: By default, only the final 2x Upscaled Image is set to auto-save. Intermediate steps are preview-only. Pick your favorite and save it manually!<hr /><h3 id="how-it-works:-the-two-prompt-system">How It Works: The Two-Prompt System</h3>This workflow uses a specific dual-conditioning setup to ensure the refiner doesn't "hallucinate" new details into your seams:<ol><li>Base Prompt (The Generalist): This handles your primary composition, character details (including NSFW traits), and lighting. It sets the stage.</li><li>Refiner Prompt (The Specialist): This is tied directly into the Ultimate SD Upscale node.<ul><li>Pro-Tip: Keep this prompt focused strictly on skin texture, facial clarity, and general refinement.</li><li>The Golden Rule: Adding too much "environmental info" or scene context to this second prompt causes artifacts every time. Less is more for the refiner!</li></ul></li></ol><h3 id="why-use-this">Why use this?</h3><ul><li>No Tiling: Optimized for clean 2x increases without the grid patterns common in high-res fixes.</li><li>Face Correction: Built-in logic to prevent "Face-Melting" during the upscale pass.</li><li>NSFW Optimized: Specifically tuned to handle skin textures and anatomy without losing fidelity during the resolution jump.</li></ul><hr /><h3 id="quick-setup-guide">Quick Setup Guide</h3><ul><li>Input: Your standard T2I parameters.</li><li>Refiner Pass: Ensure your second prompt is a "distilled" version of the first (textures and clarity only).</li><li>Denoising: Keep your denoising in the 0.3 - 0.4 range for the best balance between "new detail" and "original composition." </li></ul>
