I can't get normal maps to work in the creation kit, I've got some custom Texture sets set up, I made a normal map in Photoshop, save it as .dds etc, when I select it to go in the "Normal/Gloss" part of the Texture set, there's no preview image on the right, and it doesn't show up. Is there a certain way to save them in Photoshop? Using the Nvidia plugin I selected "3Dc XY 8bpp | Normal Map" template when saving.
