How do I separate parts?

[EtherealAxis]

I modeled a 458 in Alias, but in Keyshot, each surface is separated as a part. (http://imgur.com/NzInvJA)
There's a million of these, and I wanted to know how I can separate them. Is this something I do in Keyshot itself or in Alias?
Can I just auto group them by materials?

I'm pretty new to all of this, so any help would be appreciated! Thanks

KeyShot has 3 import options when importing ALIAS files: by layer, by material, or by object which imports the original structure as seen in the ALIAS file. It sounds like "import by materials" will solve the issue for you.
