Can someone explain to me what the difference is between the "2D Texture", "Cube Map", and "Volume Map" options for saving .dds files?


What are these 3 options used for?


I pretty much understand the other parts of the format like DXT, compressed, uncompressed stuff ... but I cant find any specific about what exactly these 3 options mean.

I don't know what volume map is, but I know the other 2.
2D texture is used for most things, cube map is only used for when you are making cube maps. If you look at a dds cube map such as those that come with many of the pixel shaders in the ultimate shader pack, you'll see they are the 6 sides of the cube map all next to each other. Setting the dds setting to "cube map" while saving lets it know that it automatically know which segments of the image correspond to each side. Then when you load the image into DBPro, and use the flag to load it as a cube map, DBP automatically knows where each side is on the image.
So unless you know you are specifically making a cube map, you'd stick to 2D texture.

Ah, ok.

Thank you
