Dear Gonzalo, > How can I generate the VBM related rendering color 3D image using > SPM.mat file ?.. With SPM5... I'm actually not sure if I got what you mean but the rendering for VBM does not work differently than that for fMRI. Just use the 'Render' button from the main panel or the render option under 'Overlays', when you are displaying the results.
