We study both oscillating and inflating curvaton scenarios when the curvaton
mechanism is caused by a hybrid potential. The source of the curvature
perturbation is the inhomogeneous phase transition that causes the modulation
of the onset of the oscillation. For the supergravity-motivated curvaton there
is a possibility of finding natural coincidence of the energy density that is
needed to affect non-Gaussianity in the curvaton scenario.
