Hello, everyone! In this video, I will create a simple shader for generating an animated star using a noise texture. And as usual, we will have plenty of parameters available to customize this effect to suit the needs of our game.

1.1.5 (2026-04-14): Added waterfall (scene and shader). Added noise_star (scene and shader).
Hello, everyone! Let’s create a simple effect that resembles a waterfall with several layers of animated water. Something like this can be useful in many 2D games, and it won’t be too computationally demanding.

Hi everyone! Let’s program a simple effect that simulates looking at a scene through ribbed glass, also known as fluted glass. It’s a straightforward algorithm based on a combination of a few basic principles.

Let’s program this interesting effect, which allows us to successfully simulate the view through a glass window during heavy rain. The shader we create this way will have many parameters and customization options, so it can be used in a wide range of situations.

Hi, everyone! It’s time to create something small in 2D again, and since simulating old devices can be very useful in games, we’ll take a look at a shader that mimics the behavior of a low-quality analog screen.

Hello, everyone! In this video, I will demonstrate how we can cut any 3D object into irregular fragments and then use them to simulate an explosion, for example, in a space shooter. We will start in Blender and complete the whole effect in Godot.

1.1.3 (2026-03-10): Added fiery_area (scene, shader and script). Added 3d_glow (scenes, shader and scripts).
Hello, everyone! In the previous tutorial, we programmed a 3D spatial shader, and this time we will stick to the same concept. In this video, I’ll demonstrate how to create a simple outline or glow effect for any 3D object in Godot 4.

Hi everyone! We’ve already created several 2D fire effects here and even one or two 3D ones. This time we’ll return to two dimensions and show how to make a slightly different kind of fire using a few layers and a somewhat different technique.

1.1.2 (2026-02-10): Added fractal_flower (scene and shader). Added wildfire (scene and shader).
Hi everyone! We have another effect on the agenda whose code fits on a single line. This time it will be a simple edge detection, which we can also use as an original way to fade out a scene, for example, after finishing a level in our game.

1.1.1 (2026-02-06): Added simple_edge (scene and shader).
Hi everyone! We’ve already covered several shaders that simulate fog, but they were mostly side effects of technologies that aren’t primarily designed for fog. This time, we’ll create a true fog shader and ook at what options Godot 4 offers for this type of effect.

1.1 (2026-01-27): Updated to Godot 4.6. Added volumetric_fog (scene, shader and script).
Hello, everyone! This is a continuation of the previous tutorial, in which we created a simple dithering effect. And as I promised, this time we’ll finish the topic by programming a shader for classic dithering with a regular structure.

Hi everyone! Let’s continue programming shaders whose code fits on a single line. This time, we’ll create an effect called dithering, which in this case means rendering an image using a heavily limited color palette.

Hello, everyone! The effect I’ll be creating in this video falls into the category of image distortion—that is, a simulation of an imperfect display or external interference. So, let’s take a look at how this algorithm works.

Hi everyone! This is the first video I’ve published in 2026, and since I wouldn’t like to start the new year with something extremely complicated, this tutorial will be easy and quick. We’ll show how we can simulate a view through something like small glass blocks.

Hi everyone! There are only a few days left until the end of 2025, so I’ll release one more video tutorial this year. Once again, it will be a contribution to the category of scene transitions. And I would say that the rotating vertical tiles look quite impressive.

Hi everyone! We’re almost at the end of the year - at least at the time of recording this video—which means we still have time for one more broken-screen effect. This time, it will be a simulation of an LCD monitor that has suffered some sort of internal malfunction.

Hi everyone! This time we’ll once again take a short break from creating shaders. Instead I’ll describe how we can test a game developed in the Godot Engine on the Steam Deck and what needs to be ensured or verified before we release our game for this console as well.

Hi everyone! Didn’t I say recently that you can never have too many scene-transition effects? I’ve just created another one that can also be customized in interesting ways, so it’s basically three effects in one. Let’s take a look at how such a shader works.

Hello everyone! This time we’ll create a shader that simulates playback from a faulty videotape. Yes, it’s a simulation of an outdated technology that’s almost unknown today, but I still think it’s an interesting effect that can find its place in many games.

Hi everyone! This time, we’ll make another transition effect, and as you can see, it simulates something like a pixelated change of the background image. Let’s take a look at how easily we can program a similar effect.

Hello, everybody! In this video, I’ll demonstrate how we can program a shader that simulates a page turning in a book, which is definitely a very effective way to transition between scenes. So let’s launch the Godot editor and get started.

Hi everyone! Let’s take a short break from post-processing effects. In this tutorial, I’ll be creating a dynamic ornament that at one stage resembles a magical portal and at another something like a fiery eye.

Hi everyone! Let's create another post-processing effect. The result can be quite useful—for example, if we want to simulate TV signal interference in our game and control the visual appearance of that effect with parameters. So, let's do it.

Hi everyone! Last time, I talked about post-processing effects and how it’s useful to have as many of them available as possible. And here we are again, because in this video we’ll be making something new in this category.
