I've been a fan of Multires and still am since it's pretty much been available. So, for those 360's or pano's that can benefit from it, I use it.
As I write this, I'm downloading my entire web site as a backup as I plan to perhaps redo major parts of it and add a lot of new content that's not currently publicly available at this time. It's been quite a few years since I've done any significant upgrades.
Anyway, back to Multires :)
Much to my shock, I really had no idea about this, I have over 92,000 files on my site. That is not a typo, it's 92,000 individual files. As a simple portfolio site I find this quite shocking. And currently being confined to a relatively slow wireless connection (130bps max, usually 80 or so) I've been downloading the site for two days and nights now. It's a bit over half done :) It's only about 7 gigabytes in total.
Just something to think about when you use multires.
Cheers,
Robert
