DDS and BUMP MAP

[frui]

I am complete newbie looking for help: If I use DDS file as texture, then there is no need to use another bump map file in the "solar.ssy"? Does DDS files already have bump map in them already?

I think, a DDS file CANNOT contain Bump map. You have to use separete file for bumpmap, if you want that effect.... But a DDS file CAN contain Specular map. (as alpha cahannel)

(But i am not sure about this infos)
