Hi Fabrizo,
As Stephan spotted you aren't actually using the same Image object, the one
you think you are dirty() has nothing to do with the one assigned to the
Texture.
I think your misakes stems from assuming that a ref_ptr<osg::Image> is an
Image, it's not it's a smart pointer to an image, so when you do a imageptr
= readImageFile("myfile.rgb"); you assigning a new osg::Image to the
imageptr, your aren't replacing the original image data.
Robert.
