Camera facing Texture

-
I forgot to post this earlier, I was approached by someone and asked how to make a camera facing texture. I recalled a similar thing from a UE4 live stream of a material based on the Palantir from Lord of the Rings made by Alan Willard: https://youtu.be/mig6EF17mR8

Camera facing Texture with some distortion effect - The texture is the logo from Ghost Recon Wildlands (It looks ghostly that's why I used this texture. 😄)




Here is the material set up I learned and implemented:
Material setup for Camera Aligned Texture 
There are a few problems with the material where if you zoom out it somehow gets bigger on cubes or flat geometry. I will need to find some way to cancel out the scaling problem so it stays the same no matter the distance between the camera and the object. As for now, I am calling this done as I need to continue working on the water shader.

Another issue is that there is this weird stretching for cylindrical/flat facing objects but I feel that is something that can be hard coded with parameters.

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...

Vertex Paint Flow map and flow map visualisation

There aren't many tutorials to go with when it comes to Vertex painting Flow maps. I was going to use the concepts that are in UnrealSimon's Flow map Tutorial:  https://www.youtube.com/watch?v=tEr3NE_XLbc   But luckily I found one tutorial by TharleVFX which uses more or less the same process as the flow map texture technique in Unreal Simon's tutorial but uses vertex painting the way I want it:  https://www.youtube.com/watch?v=hDH25HnFneQ . I also wanted a way to visualise the Flow map and distortion of the water system. It can be difficult to see in different lighting conditions especially with the unlit water system I have made. I remembered an old twitter post by H.Kudo: Flowmap Fields Visualizer UE4でフローマップの流れを可視化してみる フローマップはFusion 9で作成 ※音がでます Visualize Flowmap Fields in UE4 Generated Flowmaps in Fusion 9 #UE4 #Fusion9 #RealTime #DataVisualization #indiedev pic.twitter.com/5pDqwBHjN3 — h.Kudo (@_KudoHiroyuki) July 1, 2018 I really like how h...

World alignment (Tri-planar mapping)

-
Image
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 obje...
