Thank you, much appreciated! Yeah, they are definitely killing it. I'm excited to be a part of it :)

Still baffles me to think I could’ve had any impact on anyone’s career, but hopefully for the better! :D Means a lot. Thanks again for the kind words and all the support! <3

J'espère pouvoir contribuer positivement 😁ça va être bieng

Thanks, means a lot!

Thanks Ryan, much appreciated!

Soo, I've been diving into CommonUI lately... is it just me, or is keyboard focus still a bit of a mess? 🙃 Epic's 'Introduction to Common UI' is great, but they couldn't demo a working keyboard focus. Lots of hacks out there that kinda work, but not quite. Anyone else feel this?

🥳 New Video Alert!
In this 15-min deep dive, I walk through an experimental scriptable tool I built that fetches textures in material light functions to paint light dynamically, all in-editor. Check it out! 🔥

Oh, and sorry for the music in the clips 🤣 oopsie.

Thanks for the on-going support <3 You guys rock. Cheers

Oh! Sphere and cone tracing makes an appearance too :) One of the coolest use cases for SDFs.

This one isn’t in the video, but it’s part of the example project I just released on my Patreon.

You can bake 3D SDFs of splines using Niagara and Scriptable Tools :)

I also cover how to bake SDFs for splines — using good old Blueprints :)

I also show how to bake the SDF of a single asset, using a few hacks to create custom bounds using geometry scripting to expand the SDF.

A good chunk of the video is an overview of tools you can build to bake SDFs in-engine.

For example, one tool cuts out geometry from the scene and generates its SDF using geometry scripting.

I go over how you can quickly & easily bake your own SDFs in Blender and how to sample them in UE.
I also touch on more advanced techniques commonly used with SDFs, like approximating ambient occlusion.

There’s a fair bit of theory in the video. For instance, it’s not immediately obvious why a distance field projection might require multiple steps to actually project onto a surface.
I also briefly cover how to create custom debug tools using a few fun hacks :)

I also briefly touch on some more experimental stuff using Niagara and the Jump Flood Algorithm.

I tried to cover a lot of ground in just 1h20, so I skim over some examples.

Here, for instance, I briefly mention using Niagara’s Rigid Mesh Collision Interface to generate an SDF approximation of an animated skeletal mesh in real time.

I also show how to map a texture using distance fields — and more importantly, how to fix the infamous mipmap seam.

In case you’re wondering — yes, I go over the well-known stylized ripples effect :D

But first, I cover the theory and some key mathematical properties you’ll need to really understand how to work with SDFs.

Handcrafted subs are available! You can now mute me if you can’t stand my accent 😆

🥳 New video is out on my YT!

It’s a 1h20m deep dive into 𝗦𝗶𝗴𝗻𝗲𝗱 𝗗𝗶𝘀𝘁𝗮𝗻𝗰𝗲 𝗙𝗶𝗲𝗹𝗱𝘀.

I went a bit more in-depth than most UE tutorials out there — there’s a lot more to this topic than you might think! :D 🧵
