In Game moveing (changing shape) Spline Meshes. Collision does not move with the changing shape but stays as the original shape of the Mesh. Is this fixable?

I am using splines and spline meshes on said spline to try to emulate waves. Looks nice works, but now want to float a ship on it. Trouble is the meshes keep their original collision shape from start up (ie a flat plane) and do not alter them with the splines. So any type of interaction with them is static. I was hoping there might be some way to update the collision shape of a mesh in game. Should it be updating or am I using it for something it isn’t capable of doing? Currently using mac version.

Many thanks


wow sorted using the answer to another one of my questions on a different thing. Had to turn on complex as simple collision so that it used each poly sepuratly.
