Smooth Min&Max - math for visual people Visual Tech Art 2022-07-25 | These function are extremely powerful to achieve amazing results in graphics. They can be used for Signed Distance Fields, Landscape Height Blending and much more stuff.They come handy every time you want to pass through the highest or lowest value, but also blend them together to not have a sharp seam.My explanation is done in Desmos and the implementation un Unreal Engine 4, but as always this stuff is perfectly valid for UE4, UE5, Unity, Godot, etc ;)You can see this videos for a practical use case:Height Blending: youtube.com/watch?v=hdjRNT3DGTMTo download the Material Functions for UE4 you can follow this link: jumpeter.gumroad.com/l/SmoothMinMaxDiscord: discord.gg/YvXq3t675QPatreon: patreon.com/VisualTechArtInigo Quilez's blog page: iquilezles.org/articles/sminThanks for watching and see you next time! :)

Bringing the Spiderverse into UE5 - Tech Art exploration fun Visual Tech Art 2023-07-05 | This is not a tutorial as usual, but more of a showcase of what I've been up to lately!Since I saw Spider-Man: Across the Spider-Verse at the cinema I really wanted to try out few things that might lead towards a real-time reproduction of that amazing style.Here I managed to reach a satisfying result, given the time I put in, even though there would be much more work to do to make it actually good.Anyways this was a nice inspiration for some future tutorials I now have in mind and for further explorations :)Of course the scene I used is from the cinematic Slay, which is a free sample project, not stuff I personally made.And yes, I really need to upgrade my hardware.______________________________________________________Discord: discord.gg/YvXq3t675QPatreon: patreon.com/VisualTechArt

How to fake 8K texture quality [UE5/UE4] Visual Tech Art 2023-03-26 | Grab the interpolated CellNoise function here: jumpeter.gumroad.com/l/VTA_InterpolatedCellNoiseThis 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.Discord: discord.gg/YvXq3t675QPatreon: patreon.com/VisualTechArt
