This video explores the technical aspects of shaders and graphics in Unreal Engine 5, but these concepts are valid in any game engine that uses textures (all of them :D).
The focus is on the topic of filtering, specifically the differences between bilinear and bicubic filtering. The underlying mathematical concepts of bilinear filtering are discussed, as well as how it is used to smooth out textures.
Than we explore the concept of bicubic filtering and how it takes this technique to the next level.
The code behind these filters is analyzed, and a demonstration is provided on how to implement them in Unreal Engine 5 projects.
This tutorial provides valuable insights on how to connect art, math, and code, and viewers will gain a deep understanding of bilinear and bicubic filtering and how to use them to enhance video game graphics.

In this video we dive into the new shader pipeline that was revealed by Epic in Unreal Engine 5.2, Substrate!
We try to analyze everything as best as we can and make our own conclusion about how a new generation material pipeline might work.
The test shader you see in this video can be found on my Patreon.

In this video we go through a correct implementation of the triplanar projection mapping technique for world mapping textures in our shaders.
We discuss its properties, advantages and shortcomings. Then we build on that to create some new and better tech to fit it on the landscape material.
