Unreal Engine 5.3 - Introduction To HLSL & Scratch Pad In Niagara FX

Topic: Custom HLSL With Niagara FX Systems In Unreal

In this video we take a look at how to utilize HLSL inside of Niagara FX Systems to add custom movement/positioning and color to particles. This video also provides a very basic introduction to Scratch Pads in Unreals Niagara FX Systems.

Some things this video covers is,
- Scratch Pads in Niagara FX
- Custom HLSL inside Niagara FX Systems
- Particle/Ribbon/Mesh Renderers

Corrections:
- I said brackets a bunch of times in this video when I meant parenthesis.
- When explaining about ways to clamp/limits values here at 43:52, just for clarification.
Saturate will clamp between 0-1 and is very cheap to use, performance wise.
Abs (Absolute) will technically produce values greater than 1 in cases but it'll never produce negative values.

Learned a ton from this tutorial! Didn't know how much was possible in Niagara with custom HLSL code. Thank you so much for the inspiration.

I found this video first in the series and took your advice to watched the previous. Which I have and it feels so good coming back to this tut with the knowledge and experience built up learning for loops and structs as well as other trick you’ve shows like clockwork/anti clock. You’ve brought me a very long way and thank you!

[FlyToha]

Thank you for your amazing tutorials! HSLS very interesting, please don't stop this tutorials

[Alander]

Exactly what I!m looking for right now!

Intro short to this the day before was nice, got me excited for this vid!

You're really useful man to the society. Respect!

[vincent-gabrielc.]

Very useful, thank you so much for sharing!

I should've paid more attention in Geometry. Thanks for the video.

Great tutorial, thank you a lot! I have a question about the usage of the Engine. Owner POsition - isn't it the same as using local Space in the emitter itself?

[King-mjbn]

Is there any info regarding whether or not they'll be working to improve performance for control structures? (loops/branches/etc) Awesome tutorial btw, thanks.

Does this only work with Unreal Engine 5.3+? Im having issues with compling the scratch pad using Unreal Engine 5.2.1 on Mac OS

[doubledigital_]

great stuff, how did you make the practicals hit the ball at the end tho?

oh nvm xD haha Good job subbed!!

[ChrixB]

This is so great and looks very performant, is there any consideration with HLSL in Niagara and speed or performance? Thanks for this tutorial very useful and interesting!

[Jukerlaw]

aint spawning a lot of light render costly?

[legendofpersia]

meh never had a brain for particles. but I assume VFX artists drool over these latest updates
