This is a quickie sample file showing how to use an OSL shader script with Cinema 4D and Octane Render. You will probably need to re-link the .exr file in the OSL node.

genericLivingroom01.exr and the associated OSL shader code were made public through the generosity of Julius Ihle. You can find more info at the following link.
