Rhino7 Finding it very hard to change from 5

I am having real trouble changing to 7 from 5 (Mac) with rendering.
I cannot work out how to change render mapping or tiling.
I just need to do basic rendering to share concepts for now. 5 although limited, was OK for what I wanted, but I can’t even achieve that at the moment!
The Rhino level 2 training manual is about as much help as an ashtray on a motorbike for Rhino 7.

Has anyone done a rendering tutorial that is any use for Rhino 7?
