dxt? why do you need dxt? generals uses tga and dds files i think*
*i may be wrong, as i am not a skinner, that is just what i hear on the forums. if i am wrong then plz correct me.
if im not mistaken, i believe you unzip dxt tools into the plugins folder in paint shop pro or photoshop. Read henford's complete guide to skinning, it has all the directions.
