Hi Marco, 4:50 is a very short amount of time - it's been common in the past to wait many hours for processing something highly complex like that.

You can probably shorten the load time by setting your display mesh angle to a rougher angle like 30 degrees and uncheck "Add details to inflections". At some point here I think I'll be able to do the display meshing part using multiple cores which should help speed up file loading some.
