Hi, I'm porting the GTA 3 map, and there's underwater car and subway tunnels. How should I go about making them work? According to this post from 2016 it's not possible? https://www.beamng.com/threads/polaris-island.22770/#post-339767 But it's a huge part of the map. So really want to have them in it. I'm wondering: Is there really not way to create zones where the water plane doesn't render and doesn't affect the simulation? I've looked at water blocks, but it will take a lot of tediously and carefully placed water blocks to cover the edges of the islands, line them up so they won't overlap. But then they won't even extend infinitely, and their depth is limited, so it doesn't seem like a great solution at all. Would it maybe be possible to "hide" the water plane when I'm entering the tunnels, and display it again when I go out? Some kind of triggers? @LuisAntonRebollo Is there any way to get the shaders used on water planes and blocks and apply them to my own geometry, so I could just "fake" water by having a simple flat plane mesh with holes for each respective island, having a nice water material? Can I have the water surface without any other water properties? Thanks for an advice.
