When you use Fisheye Projection, black corners appear on the image that usually needs to be fixed by manually moving each scale slider into an approximated value where the black corners disappear, this function does that for you automatically with the exact needed number.

<aside> 💡 When you have the dy RS Tools installed, every time you create a cam node in OBJ, it will automatically have the expression on the Fisheye Projection scale parameters thanks to the OnCreated - Scripts, unfortunately for LOPs, this tool needs to be executed.
