Abstract: We evaluate in great detail one-loop four-graviton field theory amplitudes in pure $\mathcal{N}=4$ $D=4$ supergravity. The expressions are obtained by taking the field theory limits of (4,0) and (2,2) space-time supersymmetric string theory models. For each model we extract the contributions of the spin-1 and spin-2 $\mathcal{N}=4$ supermultiplets running in the loop. We show that all of those constructions lead to the same four-dimensional result for the four-graviton amplitudes in pure supergravity even though they come from different string theory models.
