The material can also be adjusted in the C4D Material manager,All render settings are concentrated in the Vraybridge render setting tabs. Which can be found under Render Setting - Effects - VrayBridge.

As it's R13, I can't be absolutely sure of the exact folders/directories etc, and you don't say if you're on Mac or Windows, but the following should hopefully help.There is a folder called Library (R13 for instance in Windows under C:UsersLaptopAppDataRoamingMAXONCinema 4D R13librarybrowser) - In there will be the list of any.lib4d (library folders) or.cat4d (catalog folders) files that hold your textures & materials if they were added to the Content Browser. So copy those from that library folder from R13 to the relative same folder in R18.If you hadn't added them to the Content Browser, then they are literally just image files, so you can add them via the Texture Paths in Preferences, but I assume that won't be what you're after if you've already tested that and it didn't work.

If they are, just make sure the R18 Texture Paths match your R13 Texture Paths and you should be fine.The best advice I can give you before doing any of this is to backup all the files in the directories, again for Windows C:UsersLaptopAppDataRoamingMAXONCinema 4D R13 and the actual MAXON program folder C:Program FilesMAXON. That way you can uninstall the program, but have a safety net in case something does go missing.Have fun with R18.nice leap from R13 in functionality.
