Hello Guys. I have a problem with meshing FLIP when flattening for ocean displacement. There's visible popping by one frame in refraction when geometry is coming out of water. Here's preview:


And here's what's going on with mesh on one frame and next one:


Anyone have any idea how to fix that problem? I've tried many solutions but without success.
- Narrow Band is turned off
- I tried subtracting collision geo from mesh but it doesn't work
- Without flattening there's no problem because of the boundry, water has thickness and it's meshed together with space around collision object.

If anyone have a workflow for meshing that kind of ascending, I would be very grateful for any sugestions.

And if that will help, I'm sharing .hip file without cache files.
