At a guess, it looks like a 'normals' problem. Are you using blender to make your stairs? If so, go into edit mode, select all vertices by hitting 'a' on the keyboard.... then hit ctrl+n to recalculate them on the outside.

 

Try reuploading your mesh and see what it looks like then.... hopefully that'll work for you. :-)
