Descriptions:
Struggling with character “face drift” in LTX 2.3? 🎬 Meet Best Face ID, the specialized LoRA designed to lock facial features and character identity across completely new scenes and camera movements!
In this tutorial, I’ll walk you through 4 custom ComfyUI workflows covering single-photo facial locking, 4-column Character Sheet integration, and 2K high-res Tiled Upscaling. We’ll also break down the strict prompt formatting and aspect ratio rules required to get 100% stable results.
🔥 What you’ll master in this tutorial:
• 🧠 The Best Face ID Concept: How this LoRA preserves facial structures while allowing dynamic actions.
• ✍️ The 4-Layer Prompting Rule: Why your prompt must start with ref_t2v: followed by specific feature descriptions.
• 📐 Aspect Ratio Math:
Single Photo: Why matching target ratios (match_target) prevents facial distortion.
Character Sheet: Why you must use native_resolution for 4-column layouts.
• 🎭 Character Sheet Creation: Generating 4-view references (Face close-up, Front body, 90° Side, Back) for full-body consistency.
• ⚙️ 2K Tiled Upscaling: Pushing LTX 2.3 to 1408×1920 / 1024×1920 without crashing VRAM.
