Thanks for you response, but yestarday I finally solve it!! (The algorithm I posted here it's not right, i use another one from dark photon).
Here there is the resolution: http://www.opengl.or...995#post1244995

Thank's for the link I get it before while searching on google.

Chek http://glm.g-truc.net/. It's a really nice library with tones of util functions, and ofcorse vectors, matrix, quaternions... It has nearly the same sintax as GLSL and you don't need to link with your project, just include it.

I think it's well calculated normal matrix.
I don't know where is the bug, I can't find it.

Here is my normal matrix calculation:
    _currentRenderableInfo.renderablePos = actor->getDerivedPosition();
    _currentRenderableInfo.renderableRot = actor->getDerivedRotation();
    _currentRenderableInfo.renderableScale = actor->getDerivedScale();
    _currentRenderableInfo.modelMatrix = actor->getFullTransform();
    _currentRenderableInfo.modelViewMatrix = _currentViewInfo.viewMatrix * _currentRenderableInfo.modelMatrix;
    _currentRenderableInfo.mvpMatrix = _currentViewInfo.projectionMatrix * _currentRenderableInfo.modelViewMatrix;
    _currentRenderableInfo.normalMatrix = Core::transpose(Core::inverse(Core::mat3(_currentRenderableInfo.modelViewMatrix)));

Check glPixelStorei( GL_PACK_ALIGNMENT, 1 ) and glPixelStorei( GL_UNPACK_ALIGNMENT, 1 ).
