so if i have more than one contribution pass suppose 3 i.e. keylight , fill light and rim light, and i want to render each light dedicated it each contribution map individually which is under my render_layer1 and i have diffuse , specular and shadow pass then i associate diffuse and specular with all above 3 contribution map and i add shadow pass to the keylight so what would i get ? 3 passes combination rendered out ? i.e. combination of 3 lights under my render_layer1 or render passes(diffuse,specular and shadow) for each of contribution map which are (keylight , fillLight,RimLight).

please help...
