[LE] Texturing a small texture over a mesh

[yojeff]

I am editing a existing static piece with Blender 2.49b (It's a piece for Oblivion). I made the modifications on the mesh, but since I extended some pieces, the texture is streched (The stones on the ramp are not horizontal anymore). I don't know how to "re-texture" with the original texture.

I did a bed (modified the mesh, then uv-unwrap smart), and that worked (The mesh was simple, and the texture was the complete bed), but I don't know how to do that sort of "tiling" (a small texture is repeated over the faces).

If somebody could give me terms to google, I would help me a lot. Thanks!

(I understand seams, I unwrapped Susan a couple of times, but the wall object on the screen shot is not a "loop", it is open)
