Regarding multiresolution output settings, what factor(s) effect or contribute to a smooth rotation and relatively quick load time? Would adding more cube size levels help smooth rotation, even though it adds more bandwidth? Would a smaller base cube face help increase load speed, particularly for rural America :)

Recent threads have clearly covered how to calculate the Multiresolution settings, but I'm wondering if you would expand on the above.

Jim Watters wrote this good summary:
[quote="JimWatters"]No need to have levels other than 1/4 the previous size by halving the width. Creating extra levels for every factor of the tile size is a waste.

if 8000 is your ideal cube width, then use:
8000, 4000, 2000, and 1000
and cube faces of 500
Making cube sizes of 500, 1500, 3000, and 6000 is just a waste of bandwidth for the user, and storage space for the content creator.

No need to downsample to a nice round equirectangular size before letting Pano2VR create cube faces.

The calculations are pretty simple.
Estimate cube size based on a value of Equirectangular width divided by 4 or Pi
divide by 2 until less than or equal to 512
to accommodate preview track of 1/4 width divide by 4,
round to nearest whole number
multiply by 2 until you are close to the starting estimate.
