Model showing white triangles - need to fix

I am trying to consolidate textures,
but when I import model into blender,
the model shows white triangles on half the model.

I am trying to put the model back into Milkshape,
but when I try and consolidate textures into one image
and put back into Milkshape it has the white triangles,
but originallly in Milkshape it has no white triangles,
only when I open it in Blender.

Any ideas on how to get model to show textures correctly?

I thougth maybe flipping normals, but would that mean that some of them are flipped and some are not.
I would have to select only the ones that need it?
