We consider B-type D-branes in N=2 supersymmetric sigma models, which describe the internal part of type II string compactifications to four dimensions. Such theories have a rich phase structure over Kaehler moduli space. In particular, non-geometric phases containing Gepner models come along with geometric ones, corresponding to smooth CY manifolds. We develop an effective tool to transport D-branes between different phases.
