We report on transmission of nonparaxial nonlocal lattice solitons at an arbitrary angle of incidence to the interface separating two nonlinear media with transverse periodic modulation of the refractive index. The energy distribution of solitons in two media can be varied by the degree of nonlocality, the nonlinear refractive index mismatch parameter at the interface, the nonparaxial parameter, the angle of incidence and the lattice parameters. Importantly, the modulation period and depth can introduce different regimes of soliton propagation in the media including refraction and trapping.
