Trouble with Blender Normal maping.

Hello to everyone.

I have a problem, I created a cave with meta balls in Blender 2.7 and separate different part of the cave to different materials, to create a better texture resolution in future.

Also I create Uv maps with with SmartUv mapping in Blender because cave is non standard form.

When I painted texture in Blender everything worked well, all became messed when I created normal maps in CrazyBump and apply it to mesh.

Here some pics they better describe my problem, can anyone please give some advice.

Thanks it helped, but still have problems when apllying Height maps, but I think I just have to spend more time with UV if I want to fix this problem.
