Applying a texture

[Sleepandeat]

Maybe my editor is bugged but I can't apply a texture to some bsp I added. Am I doing something wrong?

Hmm it seems things outlined in red are just textures... materials outlined in green can be applied. Wow that took too long to figure out, maybe I should lay off the booze while mapping haha

Though I still need to fully understand the differences between the different materials and how to use them. Any advise or insight is welcome.

Textures were used before UE3, now materials replaced them.
Materials use textures as a base but then they add different shaders and maps to them AFAIK.
