Thanks for re-posting files. Tested scripts in c4d r18 with Corona A6 rc 5 (core 1.5 (hotfix 2))
and works just fine, except the luminance material, which gives you a warning about the legacy emission value and to use the new corona light material instead.
Also a note about R18 and the recent build of Corona, is that there is a new 'corona' pull down menu option in the materials manager that allows you to create a light, portal, layered, ray or volume material. In previous versions you would have to right click, add corona material, and there were a few more material types that are no longer supported.
