The materials system is designed to pack as much information into as few textures as possible. Consequently, you will not have separate textures for alpha masks or specular levels. Instead, the engine usually stores information in the alpha channel of the base texture and bumpmap.
Several texture tools can be downloaded in the Other Tools section.
A cubemap is a texture with 6 images corresponding to the faces of a cube surrounding the viewer. These are used to render skies and reflections. The DDS texture format can store all six faces of a cubemap in one file.
Creating a Cubemap with NVidia DDS Utilities
Download NVidia DDS Utilities and place nvdxt.exe in the same directory as your 6 cube textures. All 6 textures must be the same dimensions in pixels. Create a new text file, open it in Windows Notepad, and add this text:
day_rt.png day_lf.png day_up.png day_dn.png day_ft.png day_bk.pngSave the file and rename it "cubefaces.txt".
Now Create a second text file and open it in Notepad. Add this text:
nvdxt.exe -cubeMap -list "cubefaces.txt" -output "day.dds" pauseSave the file and rename it "cubegen.bat". Double-click on this file and a console window will appear. A new DDS texture will be created containing your 6 textures.
The first 10 texture slots are available to use. Texture slots 10-15 should not be used. Texture slots 16-32 may not be supported on all hardware.
