LTX 2.3 IC-LoRA Relight (Sun Direction)
Relighting IC-LoRA that relights an exterior video to a chosen sun direction and lighting hardness, driven by a small 'light-direction ball' composited into the reference video's corner. Trained at 1280×704 × 121 frames @ 24 fps. Gated repo. Place in models/loras/.
Released 2026-07-27 · Source: Lightricks/LTX-2.3-22b-IC-LoRA-Relight (HuggingFace) — Repo also ships LTX-2.3_Relight_ICLoRA_SingleStage_Distilled.json, an official ComfyUI workflow for this adapter.

Will this run on my GPU?
Minimum: 16GB VRAM.
Recommendation: Minimal prompt: 'relight the video to match the light-direction ball.' followed by one look phrase and a direction phrase (e.g. 'hard low-angle sunlight from the right') — do not describe the scene. Strength 1.0. Exteriors only; it relights, it does not restyle content.

Common issues
ComfyUI doesn't see the file after I downloaded it▼
Make sure the file is in ComfyUI/models/loras/ (not a subfolder). Restart ComfyUI fully — the menu refresh sometimes misses new files. Filename must match exactly: ltx-2.3-22b-ic-lora-relight-1.0.safetensors.
CUDA out of memory error when loading the model▼
ltx-2.3-22b-ic-lora-relight-1.0.safetensors needs ~16GB VRAM minimum. If you're hitting OOM: • Enable Sequential Offloading in ComfyUI settings • Lower the resolution (768×512 instead of 1280×704) — both dimensions must be divisible by 32 • Reduce frame count (65 frames instead of 161) — must be 8n+1 • Use a smaller variant — see Related models below.
How do I apply this LoRA in ComfyUI?▼
Load it in a 'LoraLoader' node and connect it after your model loader. Pair this LoRA with the dev base model (not the distilled one) for the right behavior. LoRA strength 1.0 is the trained value — start there.
