+ ## Description
31
+
32
+ **LTX-Best-Face-ID — Identity LoRA for LTX-2 (Reference-to-Video)**
33
+
34
+ Keep a person's identity in generated video. Give it **one reference photo** + a text prompt, and
35
+ it generates a video of that person performing the action.
36
+
37
+ **How it works**
38
+
39
+ The reference is injected as an **overlap** latent with **TASS-RoPE (source-phase)** tagging, plus a
40
+ differentiable **ArcFace identity loss** — so the face transfers without becoming the first frame.
41
+ Rank-128 LoRA, trained on **HuMoSet** (close-up / frontal identities). Base model: **LTX-2 (22B)**.
42
+
43
+ ⚠️ **Requires the BFS Nodes for ComfyUI**

48
+
49
+ Use the **LTX Identity Transfer** node → feed the reference image → load this LoRA on the MODEL path.
50
+
51
+ **Tips**
52
+
53
+ - Use a **clean, frontal, well-lit close-up** as the reference.
54
+ - Identity is **prompt-driven** — describe the person's attributes (skin tone, hair, eyes, glasses,
55
+ facial hair) for best results. The shared workflow's \*\*Prompt Enhancer\*\* can auto-describe the
56
+ reference for you.
57
+ - Prefix prompts with `**ref\_t2v**:`.
58
+
59
+ **Limitations**
60
+
61
+ - **Close-up bias** — full-body / large-angle shots hold identity less well.
62
+ - A bare/generic prompt gives **weaker identity** — describe the person.
63
+ - The reference framing/accessories can partially **copy** into the video; a clean frontal
64
+ reference minimizes it.
