I have studied a couple tutorials and the iClone help manual. The manual says “The value of the camera lens for Panorama Videos is strict. Therefore, you are not allowed to customize this value when the Exporting Panorama feature is turned on.” Both tutorials I looked at showed frame size settings of 4096 x 2048. This is the 2:1 aspect ratio I need.

However, I cannot figure out how to get these Render frame size settings. My settings won’t exceed “Ultra HD (3840 x 2160)” and of course Custom does nothing.
