I know that Physics mod is compatible with Valkyrien Skies.
I'm creating a RP medieval server which I'm thinking to add Eureka Ships mod to create the immersion of real working ships on the server. And with the ocean of physcis mod, it will be incredible to play. However, Eureka Ships mod make possible navigate around the ocean with your ship, but it doesn't have a wind effect like those pirate ships that is moved by the strength of the wind.
I think this feature is more Eureka Ships modification than Physics Mod, but the wind physics probably would be something that physics mod should add. On Valkyrien Skies community, people talks about the "wind topic", but the devs probably doesn't wants to add wind physics on the mod.
