# LTX‑2.3 IC‑LoRA — 3D render to Photoreal

**Trigger word:** `3DREAL`

Turn a simple 3D render into a photorealistic, cinematic video.

### ▶ Run it directly on fal (no setup, LoRA built in)
**https://fal.ai/models/fal-ai/ltx-2.3-quality/render-to-real**

## 🆕 Update — v2 (`3DREAL-strong-v2.safetensors`)

A new, improved **Strong v2** adapter is now in this repo. What it adds over the original adapters:

- **Multi‑scene** — stays coherent across scene cuts / several shots within one clip.
- **Audio** — talking scenes generate synced audio.
- **Talking characters** — much better faces, mouth / lip‑sync and expression for people speaking to camera.
- **Higher quality** — sharper, more detailed, more photorealistic output.

Best paired with the render‑to‑real endpoint's `enable_detail_refine` option (extra 2× spatial‑upscale + detailer pass). File: `3DREAL-strong-v2.safetensors`. _(Example visual coming soon.)_

This is an **IC‑LoRA** (in‑context LoRA) for **LTX‑2.3** that turns a rough grey 3D viewport animation
(a simple low‑poly blockout) into a fully **photorealistic, film‑quality** video,
while keeping the **exact composition, camera move and layout** of the input.

It is made for **3D scenes and synthetic data** — Blender blockouts, game‑engine
viewports and other CG / synthetic renders become photoreal video.

## Examples

## How to use

The easiest way is the ready‑to‑use endpoint on **fal** (the adapter is already loaded,
nothing to copy):

**https://fal.ai/models/fal-ai/ltx-2.3-quality/render-to-real**

```python
import fal_client

result = fal_client.subscribe(
    "fal-ai/ltx-2.3-quality/render-to-real",
    arguments={
        "video_url": "<your 3D / CG / game render>",
        "image_url": "<optional photoreal reference for the first frame>",
        # the prompt always keeps the 3DREAL trigger; describe the photoreal result
        "prompt": "3DREAL. Make it photorealistic. A cargo ship stacked with shipping containers in a busy harbor.",
        "resolution": "720p",
    },
)
print(result["video"]["url"])
```

- **Trigger word:** `3DREAL` — always kept at the start of the prompt
- **Inputs:** a 3D / CG / game render (`video_url`) + an optional photoreal reference for the first frame (`image_url`)
- **Base model:** LTX‑2.3

## Variants — Light, Strong & Strong v2

This repo ships **three** adapters — pick based on how far you want to push the look:

- **3DREAL Light** (`3DREAL-light.safetensors`) — faithful, gentle transformation. Stays close to the input's structure, composition and motion; fewer hallucinations. This is the default used by the hosted `render-to-real` endpoint.
- **3DREAL Strong** (`3DREAL-strong.safetensors`) — stronger, more aggressive photoreal push. More realism and detail, often better on busy/complex scenes, but may drift a little more from the input.
- **3DREAL Strong v2** (`3DREAL-strong-v2.safetensors`) — **new, improved.** **Multi‑scene** coherence (holds across scene cuts / multiple shots), **audio** generation, much better on **talking characters** (faces, mouth / lip motion, expression), and **higher overall quality & detail**. Pairs best with the endpoint's `enable_detail_refine` option for sharper, higher‑resolution output. _(Example visual coming soon.)_

To run a specific variant with explicit weights, use the LoRA endpoint:

```python
import fal_client

result = fal_client.subscribe(
    "fal-ai/ltx-2.3-quality/reference-video-to-video/lora",
    arguments={
        "video_url": "<your 3D / CG / game render>",
        "image_url": "<photoreal reference for the first frame>",
        "prompt": "3DREAL. Make it photorealistic. <your scene>.",
        "loras": [{"path": "<Light or Strong .safetensors URL>", "scale": 1.0}],
        "resolution": {"width": 1280, "height": 704},
    },
)
print(result["video"]["url"])
```

Weights:
- **Light** — https://v3b.fal.media/files/b/0a9fd993/oow7bW3VueUPTukqAQkd7_3DREAL.safetensors
- **Strong** — https://v3b.fal.media/files/b/0a9fe083/H7caCyG_wt9hy_51tMEmu_3DREAL-strong.safetensors
- **Strong v2** (new) — https://huggingface.co/fal/LTX-2.3-3DREAL-LoRA/resolve/main/3DREAL-strong-v2.safetensors

## Example prompts

```text
3DREAL. Make it photorealistic. A cargo ship stacked with shipping containers in a busy harbor at dawn.
3DREAL. Make it photorealistic. A steam train winding through a misty mountain valley.
3DREAL. Make it photorealistic. A lone car driving down an endless desert highway at sunset.
3DREAL. Make it photorealistic. A grand ballroom with crystal chandeliers, slow camera glide.
3DREAL. Make it photorealistic. A coastal cliff with a lighthouse and crashing waves at golden hour.
3DREAL. Make it photorealistic. A sleek bullet train speeding across green countryside.
