Water foam cuts off abruptly at a distance

[ClockworkOcean]

See this post, there is a global distance

Distance Field is disappearing while camera moves away - simple foam shader

You could make the distance division be driven by the distance to the camera The further away you are from the camera the more you have to exaggerate the effect (give it more pixels to make up for the distance) [obraz] You can try going into world settings and adjust “Global distance field view distance” if it’s being cut off by the engine itself.

But its probably going to be a bit of an uphill struggle, as many things cutoff with distance, including shadows etc…
