Introducing a semiclassical approximation for the propagation of mesons and baryons in nuclear medium, it becomes possible to calculate inclusive spectra of various meson production processes on nuclei, respecting the angle and energy dependences of the elementary processes. This method has been applied to $(\pi,K)$ Sigma hyperon formation spectra to obtain the information about the Sigma-nucleus potential. It is also applied to $^{12}$C$(\gamma,\eta)$ spectrum, in which the eta-nucleus potential and thus properties of the $S_{11}$ resonance in nuclear medium are inferred.
