With the HDRI lighting module, you load a variety of pre-loaded HDRI images that you can use as a background in your images. In addition, these images provide physically accurate environmental lighting.\
\
**Project to ground:** You can project your HDRI images to the scenes ground plane. Resulting in a semi-spherical projection. You can learn more about how this feature can be used when creating photorealistic images [on our blog](https://www.lexset.ai/post/new-in-seahaven-realistic-hdri-backgrounds).\

**Height:** Height refers to the height of the camera when the HDRI was captured. Most HDRI images are taken between 2 and 3 meters off the ground. You can adjust this parameter to reduce distortion around the horizon, which might appear if your camera moves too high above eye level in the z axes.

**Intensity:** Set a minimum and maximum light intensity. The range will dictate the range of lighting brightness across all the images in your dataset.

**Saturation:** Sets a range for the color saturation of the HDRI background. This is a normalized value where 0 yields a greyscale background and 1 yields a full-color background.
