  We report on recent results of a calculation of the nucleon and delta masses
in a covariant bound-state approach, where to the simple rainbow-ladder
gluon-exchange interaction kernel we add a pion-exchange contribution to
account for pion cloud effects. We observe good agreement with lattice data at
large pion masses. At the physical point our masses are too large by about five
percent, signaling the need for more structure in the gluon part of the
interaction.
