Fluid Surface Simulation for multiple objects

-
The water surface at the moment was limited to the trace input and the pawn. I wanted to try and find some way to make the simulation work for any objects. On the Beginoverlap and Endoverlap nodes, I removed the 'cast to' node and made it so that any actor overlapping can make the ripples. For some reason, didn't work and it seemed to only still work for the pawn. Then I remembered that the Mesh collision settings were set to pawn only. After setting to overlap all the blueprint works with multiple objects.

Begin and End Overlap for any overlapping objects however it only works per object and not for multiple objects
However, there were two problems with the blueprint. One is the BP only reacts to latest overlapping objects. The second being the blueprint reacting to one object at a time, so if I have two objects overlapping with the blueprint at the same time, then the surface will only choose one of the objects and make a ripple. I need to make it so it works with any object.

I had an idea where I use event tick instead of the Beginoverlap and Endoverlap nodes to fix the first problem and do a Foreachloop for each overlapping object. But then that left me confused with what to do after the Foreachloop of overlapping nodes. I wasn't sure how I can make it so that the object knows where to create the ripples when overlapped.

Initial Idea to make ripples with Foreachloop for overlapping objects

I did some googling and I came across Cyberalien's water simulation and downloaded his blueprint. His blueprint didn't seem to work in PIE (Play in Editor). After spending time studying his blueprint I noticed it used a similar concept where he also used the event tick and foreachloop except it was complete and had the solution to my problem. The blueprint was cool and it also had the functionality which controls size and strength of force splat material based on the velocity and the object bounds. After adding it to my blueprint there were still some issues with it so I made some changes of my own:
Complete version of Foreachloop with the help of Cyberalien's material

The first issue is that I didn't want the simulation to constantly make ripples which can make the blueprint quite expensive. The second issue is that the whole water simulation randomly flies off when the velocity of an object goes to zero because of the division. To fix this, I simply added branch before creating the ripple so it only makes a ripple if the velocity is above zero.

Environment Showcase Concepts

I thought it's about time to start working on creating the environment to showcase the water in the best way possible. It was suggested that I create this really cool Skull Waterfall environment concept art by Andrey Egorov: However, I will be using this concept as my initial inspiration and will be making my own iteration to the environment so it will not look exactly the same as the concept. It takes a bit of time figuring out and creating some of the features for the water shader. While I do this, I can work on creating the environment so I will be working on the water shader in small increments.

Distance Field water foam

Distance Field Foam Vectortoradialvalue, DistanceFieldGradient used for U channel and DistanceToNearestSurface used for V. I thought about how texture coordinates worked and how VectorToRadialValue worked. Both being gradients in R(U) and G(V), I had a theory about creating coordinates based on using Distancetonearestsurface node as G(V) channel and have VectorToRadialValue or Distancefieldgradient node as the R(U) channel. I was initially going to use the DistanceFieldGradient node that I learned about when making the distance field flow map. This is because the node had that Texture coordinate look to it but it adds a lot to the shader instructions so I went with VectorToRadialValue node. I extracted and used maths for the R channel from VectorToRadialValue and it produced the coordinates I wanted. I then added this coordinate to the noise based foam I made earlier using Alex Vinogradov's approach. I later decided to add Distancefieldgradient node just to see if it pro

World alignment (Tri-planar mapping)

-

From reading the UE4 documentation, I found out that material functions are a bunch of nodes packed into one node. I figured out the Math behind how world alignment works by deconstructing and experimenting with the World Aligned Texture node. This node is one example of a material function. It is also widely known as Tri-planar mapping in substance painter. Material Function for Tri-planar mapping  This gave me the idea to make a block out material which can have grids, scale without texture stretching and change colours the way I want it to. I also wanted to add the functionality of animating the material. I did this by making some modifications to the World Aligned Texture material function. Modified Material function with comments to help understand which part is doing what. I found that substracting the WorldPosition from the Object Position will force the material to move along with the object and not have a weird scrolling effect whenever you move the object.
