The third drawback of classical semi-analytical model was the lack of the description of the dusty component, that for our purposes needs to be included. The semi-analytical chemo-spectro-photometric model developed by @Piovan06b allows us to overcome this issue. It takes into account not only the geometrical structure of galaxies of different morphological type, but also the effect of dust in converting the UV and Optical
