- 1). Visit the GNU Image Manipulation Program website. Blender does not support the GECK's native texture format: Direct Draw Surface (DDS). Two more programs need to be added. GIMP is a plug-in for Blender. It adds more file diversification to Blender unfortunately it also needs a plug-in to support DDS.
- 2). Download and install the DDS plug-in. The default directory is "blender/plugins." Register the two new plug-ins by restarting Blender.
- 3). Navigate to "Fallout: New Vegas" file directory. Blender can only modify the game's texture files - fur, armor, skin, gloss or glow. Open and edit the DDS file of your choice with Blender's multi-texture and texture blending modes.
- 4). Continue editing the files for your new scenario. Return to the GECK and build it. Test thoroughly before running n Fallout.
