Alessandro, Check osg::TexMat. Thats exactly the thing you are looking for.
You may be also intereste4d in osg::TexGen for automatic texture coords generated from vertex coords.

Maybe this is a silly question...anyway, how is it possible to change the number of times a texture repeats over a surface? For instance I have a model that comes with a texture already applied to it (for example a cube with the texture applied to each face) and I'd like to let the same texture repeat N times (along U or V or both) over each face. So far I can imagine only to change (by scaling) the texture coordinates of each vertex, is there any other way to achive the same result (maybe using methods from osg::Texture or osg::Texture2D)? If changing texture coordinates is the only way, is there a 'clever' way to do it? For example changing some parameter that affects every vertex in the geometry "in one shot" instead of changing each vertex coords individually...I'm just guessing... Thanks.
