Buckles in the second pic looks more realistic,better bumps,better shadows, isn't it?

I wrote a shader based on this paper, and implemented it on both Irrlicht and RenderMonkey,but the effects were not exactly.The effect on Irrlicht is not as good as that on Render Monkey I think.Does anyone kown how to improve the effect on Irrlicht?
This is the paper's site: http://hall.org.ua ...

I wonder if the model I used contains the tangents and binormals info, it need not to call IMeshManipulator::createMeshWithTangents()?

I've searched the CD3D9Driver.cpp,and found the following words:
D3DFVF_TEXCOORDSIZE2(0) | // real texture coord
D3DFVF_TEXCOORDSIZE3(1) | // misuse texture coord ...

I wrote a shader about relief mapping. When I use Render Monkey to load it, the effect is very well, but when I switch to Irrlicht,there are no bumps.
I'v heard that Irrlicht didn't import binormals and tangents from models,is it true or not?
In my shader,I calculate tangent space like this:
struct ...
