Godot Shader Pack (filiprachunek.gumroad.com)
 

Many people asked for it, so I created and released a new product: 80 shaders from my collection, ready to use in any project. Plus bonuses. 😎

Godot 4: Fire and smoke in 3D (tutorial) (www.youtube.com)
 

Hi everybody. You might remember that the fire effect created using particles in Godot 4 was one of the first tutorials I published on this channel. Since then, more than a year has passed, the Godot Engine has evolved a lot, and many things have changed in the editor as well, so the original video is no longer very usable with the latest version of Godot (currently 4.4). That's why I decided to create a new, up-to-date, and improved tutorial, which we're about to dive into.

Godot 4: Kaleidoscope shader (tutorial) (www.youtube.com)
 

Hey everybody! Let's go back to two dimensions, and take a look at how to create the effect you're currently seeing in the background of this video. It's basically something like a kaleidoscope, for which we need a source image and parameters like the number of segments, or the rotation speed. So let's go ahead and program this shader.

Godot 4: Candle flame shader (tutorial) (www.youtube.com)
 

Hey everyone! This time, we'll be playing with fire. It's not the first time I've created a fire shader, but back then, I used a noise texture and a curve as a parameter, which significantly simplified the whole process. Now, we'll try it without such tools and generate a candle flame, which, as always, will have plenty of parameters for further adjustments. So let's get to it.

Godot 4: Simple spinner shader (tutorial) (www.youtube.com)
 

Hey everybody! Recently, we created a shader that simulated an analog clock using polar coordinates, and we'll stick with this type of display a little longer. This time, I'll demonstrate how to program a fully customizable spinner based on similar principles. So, let's start coding!

Godot 4: Raymarching, part 4 (tutorial) (www.youtube.com)
 

Hi everybody! I hope the previous episodes have piqued your interest and that you're motivated to learn more tricks for rendering a 3D scene in 2D shaders. As you may have noticed, so far we've been able to change the camera's position, but not the direction it's facing, meaning it was fixed straight ahead, which has been somewhat limiting. In this video, we'll solve this problem, so that by the end, we'll be able to aim the camera anywhere or even set it up as an orbiting camera. So, let’s do it.

Godot 4: Raymarching, part 3 (tutorial) (www.youtube.com)
 

Hi everybody! And welcome back to our miniseries dedicated to rendering 3D scenes in shaders using the ray marching method. In the third episode, we will bring the previously static scene to life – adding combinations of objects, rotations along different axes and pivots, multiple lighting sources, and morphing using the so-called smooth minimum.

Godot 4: Analog clock shader (tutorial) (www.youtube.com)
 

Hi everyone! Do you remember the digital clock shader I created here some time ago? It was one of the first 2D shaders I used in a 3D project, and the result looked very usable. I think a shader simulating a classic analog clock could have a similar application, and that's exactly what we'll be creating today.

Godot 4: Julia set shader + mouse events (tutorial) (www.youtube.com)
 

Hi everyone! In this video, I would like to demonstrate a shader that reacts to mouse clicks and movements. It is a variation of a shader displaying the Mandelbrot set, which I created here about a year ago. This time, however, we will enhance it by adding the Julia set at a point chosen by the user, and we will add more control elements, all of which will be controlled by the mouse.

One-click 3D model to 2D sprite in Godot 4.4 (tutorial) (www.youtube.com)
 

Hi everyone! In this video, I won't be showcasing any shader. Instead, I'll show you a trick for easily generating 2D sprites from 3D models in Godot Engine 4.4 or higher.

Godot 4: Tilted square grid shader (tutorial) (www.youtube.com)
 

Hello everybody! In this video, I would like to create an effect that transforms a scene into its pixelated version. We've seen that before, right? But this time, we won't settle for ordinary square objectsβ€”we'll tilt them a bit to create a diagonal grid with an adjustable size. Let's take a look at how such an algorithm works.

25
Godot 4: Color palette filter (tutorial) (www.youtube.com)
 

Hi everyone! Let's create a simple algorithm that allows us to remap the colors of our scene to a predefined palette. This effect can be useful if, for example, we want to simulate the screen of an older device that only supported, say, 256 colors, and similar scenarios.

Godot 4: Rainy window shader (tutorial) in c/godot@programming.dev
[–] FencerDevLog@programming.dev 1 points 6 months ago

Thanks! The offset of UV coordinates works like refraction, localized to the corresponding cell of the defined grid. Without using a noise texture, such light refraction would be circular, similar to the magnifying glass effect. However, this approach creates slightly irregular shapes, which better simulate droplets on a window pane. If you reduce the drop_layer function to its absolute minimum, you should see the mentioned grid before the shaping and movement of the droplets.

Like this:

vec2 drop_layer(vec2 uv, float time) {
	vec2 grid = vec2(grid_x, grid_y);
	vec2 drop_uv = fract(uv * grid);
	drop_uv = 2.0 * drop_uv - 1.0;
	vec2 drop_size = drop_uv / grid;
	return drop_size;
}
Godot 4: Wet painting shader (tutorial) in c/godot@programming.dev

Thanks! About a year ago, I was experimenting with decals, but I don’t remember if it led to anything. Maybe I’ll revive this subproject.

Godot 4: Hexagonal tile shift (shader tutorial) in c/godot@programming.dev

Yes, you are right. Fixed.

How do you "separate" or "explode" a 3D mesh in Godot? in c/godot@programming.dev
[–] FencerDevLog@programming.dev 4 points 1 year ago

Assemble your objects from smaller, independent 3D meshes, which you can control separately after destroying an enemy. That's how I do it in my space shooter game.

Heh, thank you. 😎

Godot 4: Glass Door shader (fast blur tutorial) in c/godot@programming.dev
[–] FencerDevLog@programming.dev 1 points 1 year ago (5 children)

Well, Godot is a lightweight engine, so it doesn't have almost anything extra built-in. Which is advantageous because the engine itself then takes up negligible space on disk and the editor starts up within seconds, which can't be said for Unreal. But everyone prefers something different, of course. I mainly wanted to show that implementing your own blur effect can be simpler than it might seem at first glance.

Personal Opinion: the GameDev.tv Godot course isn't great in c/godot@programming.dev
