This setting is only useful in the case of animation export. ARCHICAD animation features are limited, usually, the geometry doesn't change between the frames only the camera position or the sun settings. It means you can save a lot of memory and export time if you export geometry only for the first frame, and for the other frames you only reference this geometry (via Maxwell Reference MXS). We recommend to keep this flag ON!
Render Time in Anim. (minutes) and Sampling Level in Anim.
Here you can set the Time and SL limits for the animation frames, which can be different from the ones set in the PhotoRendering Settings panel.
