The V→Pγ, P→PPγ, P→γγ, and V→PPP decays are investigated in two schemes that have had a measured degree of success in the understanding of V→Pγ and P→Vγ decays. These are (i) a nonetbreaking but SU(3)-preserving scheme with noncanonical angles θP and θV and (ii) an SU(3)-breaking scheme with canonical θP and θV. In a fit to all available data the problem of understanding the experimental ρ→πγ rate is much worse than the case where a fit is made to only the V→Pγ data.
