I already did this with the extracted files so far. This time its more complicated than in FO3. The Files are compiled in the new version of .DDS format. It needs the Nvidia decompile Plugin for PS to open them in Photoshop. The Bitdepth is the weak point in this workflow. If you try to convert them in 16bit or 8 bit which would give the possebility to save as.jpg, the colortable of the texture will be damaged and shows false colors on certain areas.
Atm. I´m decompile the textures in 32bit reajust the colors and save them as .PSD. That would recommend Photoshop to use them on other machines. I tried several Scripts to automate the recompile process to 16 bit, but what work on one texture, makes ugly results on the next one. My actual "easiest" way to do this is to open them in PS, show them in full resolution on the screen and make a windowsscreenshot after this to have a colorsave 16bit shot. Reload in PS and chop the junk away. Save as .jpg.
What a F****** work..........
