Hey everyone! It looks like our collection of shader-generated tunnels has grown once again. This time, as you can see, it’s an interesting effect created purely with points, which we can further adjust as needed. So let’s get to programming it. www.youtube.com/watch?v=NSCX...

Hi everyone! I’d say it’s time for another simple shader. I don’t think we’ve created an infinite zoom here yet, especially if it’s a cool-looking effect that we might be able to use in a game - and if not, it’s still fun to watch. So let’s get to it. www.youtube.com/watch?v=En9L...

If you’re planning to release your game on Steam, this functionality will be very useful, as it allows you, for example, to save game progress to Steam Cloud or enable various achievements. So, let’s take a look at how we can achieve this in Godot 4. www.youtube.com/watch?v=Suye...

Hi everyone! And as I promised in the previous video, today’s one will be somewhat related to the new game release, because I’ll show how I created the system for displaying and using a talent tree in that game. So let’s dive into the UI design and programming. www.youtube.com/watch?v=A35l...

My new book is out! 618 pages of tutorials, code, images, and insights about game development in Godot 4. During the first week, the discount code 20INTRO is active. filiprachunek.gumroad.com/l/advanced-g...

Hey everyone! I’ve just finished writing my book about game development in Godot, which means the time I had for coming up with new shaders was once again equal to zero. But I do have something after all. Let’s take a look at how we can create yet another blur effect. www.youtube.com/watch?v=H_ys...

Hi everyone! Let’s create another shader in Godot Engine. I was thinking about how we could combine the organized chaos represented by fractal Brownian motion with image post-processing. www.youtube.com/watch?v=mN9q...

Hi everyone! This time I’d like to show how a 2D shader can be used in a 3D scene, which can have plenty of applications in 3D games. www.youtube.com/watch?v=z2vU...

Hey! We've completed 10 episodes of the series on modeling 3D scenes using raymarching technology, so it's probably time to try something a bit simpler again. The shader you're looking at right now looks quite nice and usable, and it's not too complicated to program. www.youtube.com/watch?v=uFB4...

Hi everybody. I think there's one more topic I haven't touched on yet. It's about creating arbitrary shapes using planes with various positions and rotations. So let's take a look at how we can compute the rendering of the so-called Platonic solids. www.youtube.com/watch?v=xRMr...

Hi everybody. We'll use the Voronoi algorithm, which we know from several previous tutorials, but we'll map it onto a sphere, so we’ll end up with something like a slightly strange planet or a dead star. www.youtube.com/watch?v=Y34a...

The new trailer is out! And along with it, a teaser for the new book. Check it out. www.youtube.com/watch?v=TgXh...

Hi everyone! It looks like we’ll be spending a lot of summer with the raymarching series because I’m back with a new episode. This time, I’d like to take a look at calculating and rendering light reflections, which can be useful if we want to use reflective materials. www.youtube.com/watch?v=veSH...

Hi everybody. It's vacation season, so this week I'll fill the schedule with something simpler. I'll add a short video to our raymarching series about other basic 3D shapes and ways to modify them. Let’s do it. www.youtube.com/watch?v=Meez...

Hello everybody! The effect I’ll be creating in this video originated as a combination of the algorithm used for rendering a 3D tunnel and several applications of so-called fractal Brownian motion, which I explored while working on some of my fractal shaders. www.youtube.com/watch?v=rGr_...

Hi everyone! As I mentioned in the previous video, it’s currently July 2025, and during this holiday period, I don’t have as much time for complex tutorials, so instead, I’ll go with slightly simpler topics. Today’s video will be dedicated to polar coordinates. www.youtube.com/watch?v=pnY5...

Hi everybody. We can take a look at the next episode of our series about raymarching technology, which we use for modeling 3D scenes in 2D shaders. This time, we’ll focus on a simple algorithm that allows us to repeat the display of an object infinitely. www.youtube.com/watch?v=8Hqi...

Hi everyone! This time, we’ll take a short break from shaders and look at an equally interesting technology — particle systems in Godot 4. In this tutorial, we’ll create a trail behind a moving 3D object, with the trail based on the same shape as the object itself. www.youtube.com/watch?v=ITRu...

Hi everybody! Do you remember the tilted square grid shader we created here some time ago? If you liked it and would like to try something similar but more irregular, you might be interested in this tutorial, where we’ll create an effect similar to a stone mosaic. www.youtube.com/watch?v=02KR...

Hi everybody. This is the sixth part of our tutorial dedicated to rendering 3D scenes using shaders and raymarching technology. This time, I’d like to try improving the materials by adding textures, and briefly explain how so-called triplanar mapping works. www.youtube.com/watch?v=U5SL...

Hey everyone! Today's tutorial is a little bit special because it covers an effect that has been part of my Godot Shader Pack for several weeks now. However, I believe it deserves a more detailed explanation. www.youtube.com/watch?v=mwbg...

Hi everybody. Let's continue our series on modeling 3D scenes using shaders and raymarching technology. This time, we'll fix that detail and rewrite our code so that we can assign a different material to each object. www.youtube.com/watch?v=V_tu...

Hi everyone! I think every shader developer has at some point found themselves in a situation where they needed to determine certain values in the fragment function, especially when the shader wasn't behaving as expected. How can we solve that? www.youtube.com/watch?v=EFB-...

Hi everyone! We've already had a spiral tunnel, a circular tunnel, and a triangular tunnel. How about trying a square or rectangular one this time, which could resemble a classic dungeon-style game? It's pretty simple, so let's get to it. www.youtube.com/watch?v=KmjM...

Would you like to add great-looking visual effects to your game made in the Godot Engine? Then you're in the right place! This pack contains 80 shaders from my own collection, ready to use immediately in any free or commercial product. filiprachunek.gumroad.com/l/shaderpack

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. Now I decided to create a new, up-to-date, and improved tutorial, which we're about to dive into. www.youtube.com/watch?v=50r3...

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. So let's go ahead and program this shader. www.youtube.com/watch?v=0-G_...

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. Now, we'll try it without such tools and generate a candle flame, which will have plenty of parameters for further adjustments. www.youtube.com/watch?v=6ZZV...

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. www.youtube.com/watch?v=KS67...

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. www.youtube.com/watch?v=LTZM...

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. www.youtube.com/watch?v=Zhtr...

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. I think a shader simulating a classic analog clock could have a similar application, and that's what we'll be creating today. www.youtube.com/watch?v=1KOG...

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. www.youtube.com/watch?v=zQYq...

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. www.youtube.com/watch?v=i_XV...

Hello everybody! In this video, I would like to create an effect that transforms a scene into its pixelated version. This time, we won't settle for ordinary square objects—we'll tilt them a bit to create a diagonal grid with an adjustable size. www.youtube.com/watch?v=8WDI...

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. www.youtube.com/watch?v=a_GE...

Hi everybody. In the first part, we modeled a simple scene with a sphere, a cylinder, and a cube, and this time we will demonstrate how to properly light such a scene and calculate shadows. www.youtube.com/watch?v=f2Wn...

Hi everybody! Let's try something a little different today - an introduction to creating complete 3D scenes using shaders. www.youtube.com/watch?v=EkiK...

Let's use the Godot shading language to recreate an effect that falls into the category of many small objects following a trajectory. It consists of simple elements, ellipses, that orbit along certain curves and together create interesting-looking patterns. www.youtube.com/watch?v=_Qlv...

Hi everyone! This time, we will use a method called domain warping or domain distortion, and the result will be this infinitely changing fog that we can see in the background right now. www.youtube.com/watch?v=ys-H...

Do you remember the simulation of an old CRT monitor I created about a year ago? This time, we’ll simulate a more modern device: an LCD with its typical pixel grid and less vibrant colors. Unlike CRT, such a shader is elementary, as we’ll see right away. www.youtube.com/watch?v=-Q-N...

Do you remember the 3D tunnel created using a texture mapped onto the inside of a cylinder? This time, let's try something similar, but without textures and with a triangular shape. www.youtube.com/watch?v=Z1aG...

Hi everyone! I think that a simulation of a raindrop trickling down a window is a very nice effect, and if there are more of them, they can be both highly useful and visually striking in games. So, let’s explore how this shader works from a programming perspective. www.youtube.com/watch?v=QAOt...

Hello everyone! This is the first video I'm recording in 2025, so I hope it turns out well. This time, I’d like to show how we can use a shader to create a digital clock, which we will then control using a script. So, let’s get started. www.youtube.com/watch?v=XZPK...

Hey everybody! And welcome to the last tutorial of this year. So, how are we ending the year 2024? We will be implementing blobby objects, also known as metaballs. Yes, exactly what you see on the screen right now. So, let's get started. www.youtube.com/watch?v=AuNg...

Hi everyone! Let's add a simple effect simulating a TV signal disturbance to our collection. It actually resembles typical artifacts when playing recordings from a low-quality VHS tape, but it's up to each programmer to find a suitable use for it. www.youtube.com/watch?v=du6I...

🎄 Steam's Winter Sale is underway, and our game Whispers of Prague is also part of the event! You can grab it at a 💰66%💰 discount until January 2, 2025. store.steampowered.com/app/2767990/...

The end of 2024 is approaching, so I thought it would be good to add at least one more post-processing effect before diving into something more complex. This time, it’s again about layering, with each layer shifted differently using a noise texture and rotation. www.youtube.com/watch?v=dIt5...

Hey everyone! Let’s create a simple shader that will shake our screen or an element on the screen as if an earthquake has occurred. This could be quite useful in various platformers, right? And, in fact, it’s very easy to implement. Let’s get coding. www.youtube.com/watch?v=Kb7d...

Hey everyone! I would say that there are never enough post-processing effects, and it’s good to have as many options as possible when deciding which would fit best for our game. Let’s take a look at how we can implement a simple radial blur. www.youtube.com/watch?v=QELN...
