## 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.
