Total bytes of struct is '''1092'''. Still much is unknown about this struct. I adjusted things from OpenVIII source code. Though some numbers weren't adding up. I know the total size. So I adjusted one of the unknown bytes arrays to fit in the span.
======Time======
Time is calculated from number of frames. You basically set starting position World+lookat and ending position, then mark number of frames to interpolate between them. Every frame is one draw call and it costs 16. Starting time needs to be equal or higher for next animation frame to be read; If next frame==0xFFFF then it's all done.
