DiffusionLight-ComfyUI

DiffusionLight (Turbo) implemented in ComfyUI

This repository is recommended for non-researchers who want to extract lighting information from any image.

Unlike the main DiffusionLight repository, which requires 16GB of VRAM to run, this ComfyUI implementation enables machines with lower VRAM to operate the model efficiently.
