* **Project to ground:** _If enabled, the lower half of the HDRI is flattened to the ground plane._
* **Height:** _Height above the ground at which the HDRI was captured. Only applies if "project to ground" is also enabled._
* **Intensity:** _Relative intensity factor of the HDRI._
* **Saturation:** _Relative color saturation of the HDRI where 0 is greyscale and 1 is full saturation._
* **Frames:** _Number of frames in the final sequence. Each frame will have a unique HDRI background._
