How to use Noise Textures and create simple Shaders in Godot

You can download the whole project in this Repository @ GitHub:
And to grab more textures like the "light glow" I used here, check out my other video about Particles and Effects here:

Thank you.
This deserves more likes.
I've been scouring youtube to learn more about shaders in godot,
and I can safely say that this one's by far the most comprehensivey video out here.

[qwarybatrad]

it's a goldmine! We need more tutorials about Shaders tricks.

[seemarajput]

you are a legend of making good looking graphics in godot!!!...(i also saw it in bottomless progress log)

[rungeon]

Another incredible tutorial! I played your gamejam game a good while ago and it was when I was semi new to Godot and I thought "Wow okay this engine really can do awesome things" and since you've just pushed it further. I believe Godot needs a defining game and I believe you could be the guy to give it us.
PLEASE keep going with the youtube!

I learned quite a lot today following this tutorial. I tried to replicate everything myself on the way: making the noise generator -> learning stuff about the viewport node and noise textures, using the different noise textures for the color channels using gimp and making simple light textures using blender + krita.
And obviously I learned a bit about what I can do with shaders, which is why I watched the tutorial in the first place, in a well explained and easy-to-understand way!
Thanks a lot for this tutorial!

This can be used for a dissolve effect! I wanted to do some research about this stuff for the Godot tonight. Huge thanks!

It's a shame I missed the live Godot QA awhile ago

btw, Another great Godot content!

I like how you go over the script step by step, instead of outright writing the entire shader and just explaining line by line.
The step by step really helps visualizing and understanding the functions and effects of each line of code.

Just an Alert! In Godot 4+, you need to use this line to declare the image used:
uniform sampler2D noise_img: repeat_enable;
This will force the shader to repeat the texture.

I was looking for this.
Thanks for sharing this awesome tutorial!

[DrNabeel]

Amazing! very happy to learn Godot form you :)

[bobjones]

Excellent video. Once you explained moving the different colour channels (unlike all the other videos I watched), everything just made so much sense! Thanks!

[jmbiv_dev]

Another really cool and helpful tutorial, thanks for making this! Great explanations and super easy to follow.

[joe]

Your tutorials are great, clean explanation and easy to follow, thank you so much!

[zandernoriega]

Thx for the tut. In case anyone is stuck at the beginning, as of Godot v4.1.3.stable.official, you need to give explicit hints for noise_img wrapping to work. Ie. `uniform sampler2D noise_img: filter_nearest, repeat_enable;`

Top notch content! Instant subscribe :)

[RakkaRage]

Thanks. in Godot4: need to set repeat on texture node (not import) and on uniform: uniform sampler2D noise: repeat_enable;

[bariscanbilgin]

This was an incredible tutorial thank you very much ! 🍀

[dogeatdog]

Thanks you! Finally starting to understand Shaders

[BramwellWilliams]

Awesome! It would be nice if the code was more zoomed in though, just for readability on mobile

[marcosadrian]

Wow amazing tutorial rafa as always! Very well explained and as a lot of uses. Give a like in bout accounts but deserve even more 😉
