I cannot render sketchup section


So I’m using Sketchup Pro 19 and Vray 4.00.02 and tried to render a section but it seems like it doesn’t work.

I watched some videos in youtube and whenever they create section plane, theres a clipper generated in vray geometries but none found in mine.

I tried rendering a section before and i remember it worked but now it doesn’t and it is getting on my nerves.

Can anyone help me with this problem? Thank you.
