how do I add a uvw map modifier?

how do I add a uvw map modifier?

You pick Unwrap UVW from the modifier list.

what do i do after that? im confused.

b/c i was told tht my problem with 3d Max was b/c of that, but i went to unwrap but im really confused, even with the tutorials. I did stuff to the priest but i nd to edit it in the mapping or something??

What i was exactly told was "Part of the mesh isn't uvw mapped. If you add a uvw map modifier to it the export should work." but all i did was delete parts of the priest, i have no clue what im doing...

any1?

After you added the UVW modifier, so gotta choose "Select faces" (which you find by pressing the + ). Then you choose what part of the model you'll unwrap, then press Planar Map, and then Edit.
