Hello Teokoles
first of all, thank you for the great water 
I am stuck on one thing, though: I can not get the physical water to receive shadows from static mesh objects (e.g. a static mesh ship, not using buoyancy) using static lighting.
A stationary directional light will produce shadows, but the shadows disappear again after building the lighting. Only when I move the static mesh with the widget the shadow appears, but disappears again after building the lighting.
A movable directional light creates shadows as I’d like them.
But I can’t use dynamic lighting due to performance reasons.
Is there a way to bake the shadows onto the physical water with static lights?
