Lighting interiors can be tough, especially if there is no interior illumination, and you're relying on windows to light your scene.

With Iray Window Lights, you can simply drop one of the two included light props outside of your window, customize it from a range of presets, and hit render.

Two lights perform two separate tasks, a Pano Light, and a Window Light. The Pano light is wider, and uses high resolution images as backgrounds, which is ideal for large windows or even filling bare backgrounds.

The standard window light is perfect for smaller windows and has an array of environments at different times of day, and in different weather conditions.

Each light has two separate layers, the background and the invisible ghost light. The backgrounds will fill in and gaps behind your window, whilst the light will force emission through your windows.

Having these elements separated means you don't have to have an extremely bright background just to light your interior.

 These lights are very easy to use. Just position them outside of your window, apply the included presets to either your background or your light, and you're good to go.

The strength of the lights range from very subtle to very bright, so you should find a sweet spot for your renders.
