  Tidal features provide signatures of recent mergers and offer a unique
insight into the assembly history of galaxies. The Vera C. Rubin Observatory's
Legacy Survey of Space and Time (LSST) will enable an unprecedentedly large
survey of tidal features around millions of galaxies. To decipher the
contributions of mergers to galaxy evolution it will be necessary to compare
the observed tidal features with theoretical predictions. Therefore, we use
cosmological hydrodynamical simulations NewHorizon, EAGLE, IllustrisTNG, and
Magneticum to produce LSST-like mock images of $z\sim0$ galaxies ($z\sim0.2$
for NewHorizon) with $M_{\scriptstyle\star,\text{ 30 pkpc}}\geq10^{9.5}$
M$_{\scriptstyle\odot}$. We perform a visual classification to identify tidal
features and classify their morphology. We find broadly good agreement between
the simulations regarding their overall tidal feature fractions:
$f_{\text{NewHorizon}}=0.40\pm0.06$, $f_{\text{EAGLE}}=0.37\pm0.01$,
$f_{\text{TNG}}=0.32\pm0.01$ and $f_{\text{Magneticum}}=0.32\pm0.01$, and their
specific tidal feature fractions. Furthermore, we find excellent agreement
regarding the trends of tidal feature fraction with stellar and halo mass. All
simulations agree in predicting that the majority of central galaxies of groups
and clusters exhibit at least one tidal feature, while the satellite members
rarely show such features. This agreement suggests that gravity is the primary
driver of the occurrence of visually-identifiable tidal features in
cosmological simulations, rather than subgrid physics or hydrodynamics. All
predictions can be verified directly with LSST observations.
