Hello,

is there a special way, how to programm objects, that they look like swimming on a water lake or on ocean, moving up and down, for example trash on water like bottles. Has somebody an idea, how I can do this.

Thanks. Jojii

Hi!

Currently you cannot do this in BP project. Because this feature requires C++ code.  
This is tutorial about how to create Target Lookup node which convert a height map to world position.

I don’t need this, because my lake has not big waves. I only need a little bit moving up and down, maybe with a timeline or such, but my code doesn’t work and maybe somebody can post a simple BP code for that.

Thanks. Jojii
