Materials showing up as flat collor

[UDKUser]

For some reason the materials on my static meshes have begun showing up in flat color. On BSP it still shows fine.

How can I get it to show up on my static meshes?

Have you UV mapped your cube?

Yep, standard unwrap that's worked before.

Reinstalled, still rendering as one color. All the standard meshes work fine.
