There's a sketchup file I'd like to use for a fairly large mod I'm making, but I can't figure out how to convert the files to .nifs. I can export them as obj and from there fairly easily get them as a nif, but then they don't have UV maps.

None of the tutorials seem to go over specifically how to get the uv maps from sketchup files to work, though they go over collision data (which was never a problem in my case; I was just going to import it over another nif anyway).

Here's the thing I want to convert, if anyone wants a go at it:
