Most tutorials about hero waves are from 7 years ago, and I have tried different approaches to cast an ocean grid, or spectra to a slightly rounded surface but in Karma I only get a flat plane when using houdiniocenaprocedural.

The only way more or less I could render anything was importing the preview ocean_plane converted to a polygon.
From the same ocean_preview plane I couldn't get the baked displacement maps to afect the ocean material, so I made the polygon resolution very high to get some bump. I am pretty sure this is NOT the way to do it.

Also tried to use the SOP modifier inside LOP, to project the ocean (ray) on a sphere with no success.

I am out of ideas on how to do it...
