Vertically layer a layerable BSDF such as dielectric_bsdf, generalized_schlick_bsdf, sheen_bsdf or thin_film_bsdf over a BSDF or VDF. The implementation is target specific, but a standard way of handling this is by albedo scaling, using the function 'base*(1-reflectance(top)) + top', where the reflectance function calculates the directional albedo of a given BSDF.
