Colour = blabla_1_d.png (diffuse map)
Ambient Occlusion = blabla_1_ao.png
Normal map = blabla_1_n.png
Specular = blabla_1_s.png
Note: a normal map and a bump map are different but essentially do the same thing but you might have to change an option in C4D to ensure that the bump is read properly. Ive used cinema before but not 100% how it reads bump/ normal maps.
