Here are presets for rigs based on 2, 3, or 4 Kodak SP4k cameras. Based on a sample shot specially for this calibration courtesy of Skyler Baird. This is for normal use. For underwater shots, there is a separate preset. Careful center the lens crop circles for each camera.

Hi Roman, I have a .grp preset for an underwater Kodak 3x rig, how do I import the preset or what file path do I place the file in? Thanks, Rick
