It already says In the eula that you can do anything with light settings other then copywrite them and as I said EUlA or no EULA I don't think they are copywritable your first point would be the general argument "Lights settings, camara positions and so on are general concepts for 3D programs.". you're not importing the lights just the settings the CL EUlA cant stop you from importing those settings. original content however is always copywritable by their creator and that right cannot be taken away by a EULA agreement even if they wanted to, original content cannot be copywrited untill after it is produced.
