Hello @LaggyLuke. Do you mean the check box called “Ocean foam” in the river material?
This is the only foam parameter I see in the Material Instance for rivers.
Also, are you talking about the foam generated by the river speed or the one around the character interacting with it? I was trying to make the speed related one work.
I’m interested in the steps you’re doing if you managed to make the foam work for rivers.
Even with the FluidSimBP in the scene, I never seem to get them.
