<h1 id="workflow-features-and-setup-guide">🚀 Workflow Features &amp; Setup Guide</h1>Place the official H3_NSFW_Physics_Engine.txt file into the directory path \ComfyUI\models\LLM\prompts, and select H3_NSFW_Physics_Engine.txt in the system_prompt field of the prompt expansion model node.&gt; ⚠️ Important Notice: This workflow incorporates an acceleration LoRA and Kijai's SageAttention node. Please ensure you download the required LoRA and custom node before running.<h2 id="key-features">🌟 Key Features</h2><ul><li>MiniMax H3 Prompt Synthesizer: Built-in prompt engineering node supporting multi-dimensional parameter assembly (Shot Type, Perspective, Lens Optics, Camera Movement) with bilingual presets. Includes an integrated side-by-side web workspace (with right-edge hover focus) and safe image drag-and-drop functionality.</li><li>Gemma 4 12B IT QAT Integration: Integrates Gemma 4's thinking mode for deeper reasoning, high-precision prompt interrogation, detailed captioning, and complex tag conversion.</li></ul><h2 id="required-custom-nodes-installation">📦 Required Custom Nodes Installation</h2>Open your terminal, navigate to your ComfyUI <code>custom_nodes</code> directory, and run the following commands: <pre><code>cd ComfyUI/custom_nodes

# 1. MiniMax H3 Prompt Synthesizer Node
git clone https://github.com/mizukir0418-gif/ComfyUI-MiniMax-H3-Prompt_Synthesizer.git

# 2. LLM Text Processor Node (Required for Gemma 4)
git clone https://github.com/KingManiya/ComfyUI-LLM-text-processor.git
</code></pre><h2 id="llm-model-setup">🧠 LLM Model Setup</h2><ul><li>Model Download: Download <code>gemma-4-12b-it-uncensored-GGUF</code> or the recommended variant from <a target="_blank" rel="ugc" href="https://huggingface.co/SC117/gemma-4-12B-it-heretic-QAT-GGUF">SC117/gemma-4-12B-it-heretic-QAT-GGUF · Hugging Face</a>.</li><li>Storage Path: Place the <code>.gguf</code> file inside: <pre><code>ComfyUI/models/LLM/
</code></pre></li></ul><h2 id="critical-fix:-updating-llama.cpp-backend-(gemma-4-compatibility)">⚠️ Critical Fix: Updating llama.cpp Backend (Gemma 4 Compatibility)</h2>Because Gemma 4 utilizes a new architecture, the older default backend built into the LLM node will throw an error (e.g., unknown projector type or inference failed) on its first run. Follow these steps to update it: <ol><li>Download the Latest Backend: Go to <a target="_blank" rel="ugc" href="https://github.com/ggerganov/llama.cpp/releases">llama.cpp GitHub Releases</a> and download the release zip matching your GPU/CUDA environment (e.g., Windows x64 CUDA 13 or CUDA 12).</li><li>Locate Target Directory: Navigate to the following folder inside your ComfyUI installation: <pre><code>ComfyUI/custom_nodes/ComfyUI-LLM-text-processor/vendor/llama.cpp/b8840/win-x64-cuda13/
</code></pre></li><li>Replace Files: Extract the downloaded zip file and copy-paste all extracted files directly into the <code>win-x64-cuda13</code> folder, overwriting the existing ones.</li><li>Restart: Restart ComfyUI to apply the updates.</li></ol>DISCLAIMER &amp; TERMS OF USEThis workflow is provided strictly for educational, technical research, and sex education/learning reference purposes only.
