The optical potential approach for low-energy scattering of η mesons on three-body nuclei is compared to an exact treatment of the η3N system using four-body scattering theory with separable interactions in s waves only. The higher-order terms including the interaction of the struck nucleon with the surrounding nuclear medium and virtual target excitations in between successive ηscatterings are found to cause important corrections. Effects of final state interaction in ηphotoproduction on H3 and He3 are also studied and sizable contributions beyond the optical model approach are found.
