deferred shading mipmapping problem

[white_waluigi]

I have a problem with high res Noamal mapping. I'm using the Deferred Shading code from the DS Sample for normalmapping aqnd standard Ogre Mipmapping. But the results are pretty ugly, you can see the transission between MMs pretty clear, without Normalmaps however, it looks fine:

So is there a way to make the transistion a little bit smoother? Or does anyone have any Idea what causes this?
If I disable MipMapping, there is no transsission, but it looks pixely as hell.

in your material, what kind of filtering do you use for the normal map?

Thx for the Hint I changed texturefiltering to Anistropic, and now it looks fine.
Problem solved, it was on Biliniar and point mipmapping, which dont seem to work well with mipmaps.
Ogre::MaterialManager::getSingleton().setDefaultTextureFiltering( Ogre::TFO_ANISOTROPIC);
