I loaded the models sent to me in Lightwave and the glass looked fine , except for a hole  and the 'sauce' was ok but for some non-planar n-gons.

I emailed a reply with some suggestions for those .

It all imported into Poser 7 sr2 with no problems, just using center and floor options.

The pic is what I get as a render with a simple color texture applied to the glass

I examined the obj files in wordpad for any issues with continuation lines and there are none.

Sorry, but I dont see a problem with the models. There may be a bug in obj import :(
