HELP: Vray error with section plane

Hello, my problem is the following: I am trying to do interactive render with Vray and there’s no problem with that. Then, as soon as I create a section plane, and I try to do the same interactive render, it shows this message below in the screenshot. Of course, as you know, section planes are ESSENTIAL for renders, as well as for being able to model in detail… It’s impossible to work by only activating/deactivating layers. I wonder if there’s any alternative fixing with Vray clippers (which I don’t know how to use), but I would still love to solve the traditional way. PLEASE HELP :slight_smile:
