Using Ocean bakes (from Ocean modifier) to Displace a Plane with Geometry Nodes - HOW?

Question

I have created a near-perfect ocean for my scene using texture displacement. Basically I just made two different ocean bakes and then used them blended together in the displacement channel of my plane.

However, I ran into an issue when I realized that I need Geometry Nodes for the spray effect. My issue is that I can't figure out how to recreate my ocean with GN, so that I can then use the Ocean Spray bake to create points for the spray geometry.

This what my material node looks like:

For this result:

How would I go about rebuild this node setup in Geometry Nodes? Take note that I have two different bakes and they are scaled differently, then blended together.

I'm stumped on how to build a GN setup that would have an identical outcome, so that I can further amend the nodes to add Spray.

Answer 1

Not an answer, but perhaps a lead: I'm using the addon "Advanced Ocean Modifier", which uses GeoNodes to add spray. It's a paid addon, but sometimes it's cheaper to buy a setup than to figure it out by yourself :-)

This setup (including more complex material and no/less displacement I think) does render twice as slow as your cached solution over here. And your shader works in a circle, while the Ocean Modifier, basically a layer over the Blender Ocean deformer, uses rectangles. Circle seas give better horizons. But still, perhaps you can inspect their GeoNodes setup.
