In all honesty, I keep bouncing between learning Blender and learning Unreal on a weekly basis.
I haven’t done any real testing with the fountain map but I intend to at some point.
What is holding me back from Unreal is that Epic hasn’t released what UE can do with water simulations yet (just some hints from Asher Zhu). Fluid Ninja and Fluid Flux have done some great work and Embergen has been working on LiquidGen but hasn’t released anything yet.
