Hello! I’ve used UDK in college and for some projects, and while I am much, much, much happier with UE4, there is one thing that really irks me in it: water. UDK had fluid surface actors, screen capture reflect actors, and some very nice water rendering to get good reflections, lighting, interactivity, etc, and UE4 just doesn’t have any of that. Reflections aren’t great for large bodies of water, specular reflections are completely missing for all translucent objects, and there’s no interactivity, which is quite mind-boggling because just about everything else in UE4 got a massive upgrade.
So to bring back some of what UDK did right with water, I’m just wondering if it’s possible to bring back the phong specular model in a separate forward rendering path. I’m not sure if this is even possible, but a lot of what makes water in UDK look so good is that Phong specular model. Combined with perfect reflections and interactivity, it was absolutely brilliant. If there is any way to bring back these features, I’d love it!
For UE4 I created my own light vector blueprint and my own Phong specularity, and the water I managed to make looks gorgeous. It really makes me wish there was a forward shading path with phong specularity and some better tools for this.
