K... Exported as .obj with default settings... Can't seem to upload .obj here... so here it is: http://s000.tinyupload.com/index.php?file_id=02317076087762468233
It is still a weird decision to turn it on by default considering how that is usually the first thing people complain about when they use modo for the first time.
@Shyralon: Switch matcaps to a gray lambert. The default skin one kind of sucks for looking at the sculpt critically. It makes everything feel too soft.
Turn on physicalize and set it to default in the material ID`s that your object is using. This is not recommended though, you should really use collision primitives...
