Hi dear authors,

for complex scenes, there may be multi lights. how should I change the code to fit such cases?

Thanks,

Hello @lcc815 ,

We currently support one unique HDR probe (which can represent quite complex lighting). We assume that the lighting setup is constant for all images in the dataset.

If you are asking for multiple lighting scenarios for one scene, that is not currently supported, but an extension to optimize N HDR probes for a setup with M images, where N < M could likely work. For example, an object captured in two different lighting scenarios, and you know, for each image, which of the two lighting setup was used.
