We propose a system of fermionic screening fields depending on a continuous parameter b, which defines eta-deformed OSp(n|2m) sigma-model in the limit b to infinity and a super-renormalizable QFT in b to 0. In the sigma-model regime  we show that leading UV asymptotic of the one-loop RG group flow equations coincides with perturbation around Gaussian theory. In perturbative regime b to 0 we show that the tree level two-particle scattering matrix matches the expansion of the trigonometric OSp(n|2m) R-matrix.
