Unreal Engine 5 Tutorial - Technical Shading - HLSL Basics / Simple Shapes

In this video we look at how to draw shapes like a circle using math in HLSL. We also take a look at how to go back and forth between HLSL and Unreal shading nodes.

This tutorial is aimed at a practical and artist friendly approach to getting familiar with the thought of shader code and understanding the manipulation of numbers that produce the results we see.

Seriously it's the best shader 101 i've ever watched . Congrats. Now i' going to binge all of your content.

Good Work! One stop shop for getting hlsl into a shader easily

Nice video but I was really hoping to see more than one type of shape ("Simple Shapes") ... was kinda expecting more. Everything else is awesome from this creator as always

Thank you very much for your lectures. Very very informative to learn.

Thankyou for another great tutorial! I'm binging through the series, So it's probably a bit late to ask.. But I'd love it if the code could be magnified a bit as it's a tad hard to read.. But I'm managing aha

Amazing tutorial man! Waiting for another one

Thank you for sharing the knowledge. I am interested in HLSL in UE5.

but we didn't get the power of the float d = length(pos-uv); how did we create a circle with that? doesn't this mean we just get the info about the offset amount in vector length with this? edit: got it. we are using "pos" as the center point and compare uv coordinates to that. if it is closer, it will be white. so our center is in 0.5, 0.5 so that results in a circular gradient.)

[pygmalion]

for these examples we wouldn't want to use hlsl tho right? cuz just a material function can be more efficient.

[cmitchell]

Can you use HLSL's Rand with custom nodes? I've been trying but must be doing something wrong.

Why the x power + y power not the same result with x*x + y*y?

[EliasLeo]

i feel stupid, why is the result of R^2 + G^2 different from R*R + G*G ?
