How do you export a model with a Lowrez from mshex? If that won;t work, how would I get the model to use the normal model as a lowrez?

I think you just take the original .msh copy it and add _lowrez to the end... Im not sure though

I work like this:

1) make the model
2) add texture
3) create a null which is called "dummyroot" (without the quotes)
4) open the window selection
5) select the model that did drag on dummyroot
6) copy the model and rename
with this extension "nameofyourmodel_lowrez" (without the quotes)
7) click the middle mouse button over dummyroot and then exported to the folder MeshEx with Crosswalk 2.6

Of course, since it's an exact copy it's not that low-rez; I wouldn't reccomend doing this for more complex models.
