I was wondering if anyone knows of some way to split post process effects over two halfs of your camera. I've been watching the new fluid simultations videos on the community hub and everytime they showcase water they have this insanely beautiful transition where your camera is at some point showing above water and the lower half is showing the underwater. They seem to have two seperate post process effects active and have them split by a mesh. This looks really really cool and I would kill (not really lol) to get this effect in my game project (signature).
Here is a screenshot I took from the fluid simulation by render target video.
Oh Unreal lords, please share your knowledge. I just need to have this in my project. xD
EDIT: Waaiiit a min.... Are they using a atmospheric fog for this? And just setting the altitude value at exactly the height of the water surface? Meaning it's fake? Please tell me I'm wrong. Tell me there is some magical trick to do this.
