I am using the ocean modifier along with some interesting arrangement of modifiers to make it look like its breaking on a beach.
I'm actually quite pleased with the way it looks..but I want to try to add that last bit of realism by attempting to emulate some foam.
I would be happy with just being able to colour the tips a bit white, or if there is a way to generate this foam that'd be great - I'm not that familiar with the ocean modifier. I know there's a way to get foam but don't know how to use it properly.
I tried using a geometry node and separate xyz node to use z in a colorramp, but it doesn't look good.
I tried using the pointiness from the geometry node but it didn't actually do anything? I tried applying my modifiers first too to see if that was why, but didn't seem to give me anything.
I also have vertex weighting for vertices close to shore as part of the modifiers I used to shape the waves at the beach:
Ideally I would be able to use this as an input for a shading node?
Any ideas on how I could make these waves look a bit more real?
Would appreciate it. Using 2.83.
UPDATE
I was able to find a hack to modulate the UV map using the vertex weight so I can access it from a shader node, using this trick:
(Nathan's answer)
The current look, and shader node set up:
obviously it's a start, but the white/foam is not really on the crest of the waves.
Please any suggestions!! I would really appreciate it
