Let R be a maximal rigid object in and let Γ be the endomorphism algebra of R. Let F be the functor $Hom_{}(R,-): → mod Γ$. We prove that any τ-tilting module over Γ lifts uniquely to a maximal rigid object in via F, and in turn, that projection from to mod Γ sends the maximal rigid objects which have no direct summands from add SR to τ-tilting Γ-modules, and in general, that the Γ-modules corresponding to the maximal rigid objects are the support τ-tilting modules.
