MWCS Tilesets!

[Onilink01]

Hi all i'm just having some problems with MWCS. I seem to be able to swap M2s fairly easy but when I change Tilesets it never really changes anything.

I did however notice that each tileset there is 1 or more faded pictures of the tileset?
Do I have to change those aswell?

Thanks any help is greatly appreciated!

Tilesets come in pairs of the real texture and the fake-bump-mapping one. The second one is needed to calculate the reflections of the light, you can see ingame. They have to be called TEXTUREFILENAME_s.blp.
