Edited portraits not appearing correctly

Hi guys. I'm a 2k11 newbie, and I just started updating some portraits. I've used GIMP and the 2k11 Mod Tool to create and import new .dds files to portrait.iff and portrait_hi.iff. The new portraits seem to appear correctly in the menu's

. However, when I make substitutions, the previous portrait textures are being combined with the new ones to make for a very odd look:

Any ideas on what I'm doing wrong and how I can get the updated portraits to appear correctly on all screens?

You do not have the required permissions to view the files attached to this post.

make sure when you save your dds files you save the mipmaps too, or else youll have those issues

Ugh, sorry, I feel stupid for not remembering to do that. It's always the simple things we forget, right?! I resaved the dds files with mipmaps and things are much better now. Thanks so much for the quick response!

glad to hear it helped
