Results are presented on a study of resonant structure in the {omega}{eta} and {omega}{pi}{sup 0} final states produced in {pi}{sup -}p interactions at 18 GeV/c where {omega}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0}, {pi}{sup 0}{yields}2{gamma}, and {eta}{yields}2{gamma}. Final states, such as {omega}{eta} and {omega}{pi}{sup 0}, which contain a vector meson, are allowed in the extended flux-tube model for the decay of hybrid mesons. In the {omega}{pi}{sup 0} final state, the data exhibit the well-known b{sub 1}(1235) and the {rho}{sub 3}(1690) resonances. A one-pion exchange mechanism is clearly seen for the {rho}{sub 3}(1690). A detailed partial wave analysis of both {omega}{eta} and {omega}{pi}{sup 0} is currently in progress.
