Kind of goes without saying... but..... you can use Light Looks to create distinctly different lighting moods or styles for the same shot. These are all stored in the same HDR Light Studio project. So once you or your client chooses their favorite Look it's easy to select it and produce the final lighting for your scene or to make further tweaks. Previously you would need to save out multiple HDR Light Studio projects and load them, which is far slower and also means all those lighting designs are not stored in the host 3D software's project.

Save off iterations as the lighting design evolves over time, a history of your lighting project. Then easily compare earlier versions with the current version to decide if the lighting has moved in a good direction.
You can easily go back to an earlier version and carry on where you left off.

In a single HDR Light Studio project, you can now set up a lighting design for each camera view. So you no longer need to save multiple scenes file in your host 3D software for each camera.

Imagine you have a product to light, but it comes in different colors. Set up a base lighting 'Look' as the foundation for your lighting. Then create Child Looks to augment the lighting for each colorway, i.e. adding different lights on top of the common base. So you have a family of lighting designs that have a common theme.
