I realise its the octane render file, but i can't seem to import and object file into octane render

greetings!

Hello,

I just installed the octane render demo, but it can only open ocs files and no obj files. So where can i find a ocsfile to try it out?
Also i would like to know of octane renders let you create spotlights or do you have to create them in your modelling program?

greetings
