Hello, everyone! Are you working on a 3D game in the Godot engine and would like to simulate day and night based on the current time? This sky shader might be just what you need for your project. Let’s take a look at how it works and how to program it. www.youtube.com/watch?v=azSG...

Hello, everyone! In this video, we'll create a cracked screen or shattered glass effect through which we can observe the game scene. We'll combine several programming techniques we've used in previous tutorials, and the result will definitely be worth it. www.youtube.com/watch?v=e2Rz...

Hello, everyone! Let's create a simple shader that distorts an image into a spiral, simulating flying through some kind of abstract tunnel. It's a very simple piece of code, which I will now explain in detail. www.youtube.com/watch?v=7YEf...

Hello, everyone! It's time for another simple tutorial that could find its use in a 2D game. This time, we'll be shaking an image or the screen using a slightly more sophisticated algorithm. So let's program it. www.youtube.com/watch?v=HvdD...

Hello, everyone! Let’s again create a spatial shader for a 3D object. This tutorial is special because for the first time I will touch on a function that I have completely ignored so far. It is the function called light, and I will show how we can work with it. www.youtube.com/watch?v=iJGX...

Hi everyone! I think after several relatively long videos, it would be nice to do something simpler for a change. We’re going to program an effect that simulates looking at an image through square-shaped curved glass. www.youtube.com/watch?v=Bv_K...

Hi everyone! Maybe you remember the first tutorial I published this year, which demonstrated a simple algorithm for distorting an image divided into tiles. This time, we'll take that idea a step further and create a wall made of differently distorted glass bricks. www.youtube.com/watch?v=mXFP...

Hello, everyone! It seems that the cave tunnel shader I created here recently was quite successful, which pleased me enough that I decided to add another effect based on a similar principle. So, let's take a look at how we can program it. www.youtube.com/watch?v=vfmB...

Hello, everyone! We previously looked at a shader that generated spiral-shaped objects, but back then it was just an elementary implementation. This time, let’s try something more practical, namely a distant view of a spiral galaxy. www.youtube.com/watch?v=n3TL...

Hello, everyone! Let's expand our collection of tunnel effects with another shader. This time, we'll try something more irregular that could resemble flying into some unknown cave. www.youtube.com/watch?v=d-oo...

Hello, everyone! I’ve created a shader here before that simulated a simple animated star. This time, we’ll take that creation to the next level and create a much more interesting type of star using a somewhat more complex approach. www.youtube.com/watch?v=unKl...

Hello, everyone! Let's create an effect that resembles boiling lava viewed from above. It's also a great demonstration of using four-dimensional noise and slicing it into three-dimensional layers, resulting in the characteristic flowing lava animation. www.youtube.com/watch?v=95GQ...

Hello, everyone! For the third time, we'll be working with a shader based on a line graph with many vertices. This time, we'll program an effect that loosely resembles a seismograph or another instrument with a similar display. www.youtube.com/watch?v=pvZq...

Hello, everyone! In the previous video, we created a simulation of an electrical discharge using a line with multiple segments. This time, we'll create something like an ECG monitor that displays the characteristic heartbeat waveform. www.youtube.com/watch?v=GgG8...

Hi everyone! Let's create another 2D effect that we can use in a game as an obstacle or an energy weapon. We'll program an animated jagged line that resembles a lightning bolt or an electrical discharge. www.youtube.com/watch?v=vmCY...

Hello, everyone! Let’s again create a spatial shader for a 3D object. This time we'll create a simple flag, make it wave gently in the wind, and demonstrate how we can dynamically control this effect in the vertex function. www.youtube.com/watch?v=d1y8...

Hi everyone! Let's make something simple, because it's the beginning of July, and I'd rather relax than program overly complex shaders. We'll create a simple image warp effect that fits into a single line of code. So let’s go ahead and program that one line. www.youtube.com/watch?v=LliK...

Hello, everyone! In this tutorial, I’d like to return to simple effects that don’t require any image input. This time, we’ll create something like an animated nebula, which can be an interesting visual enhancement for many space games. www.youtube.com/watch?v=xP9d...

Hello, everyone! After the previous tutorial, where we reached a new record of 25 parameters, let’s take a look at something simpler. We’re going to create an effect that belongs to the category of scene transitions and resembles wiping a blackboard with a wet sponge. www.youtube.com/watch?v=Muhe...

This is the second part of the tutorial in which we create a shader for simulating old film projection in Godot 4. This time, we will complete the entire effect by enhancing it with various scratches, stains, and other types of damage that can appear on film strips. www.youtube.com/watch?v=ycSX...

Hello, everyone! We already had a shader that transformed an image into an old photograph, and this time we’ll take that effect to the next level. I’ll show how a similar approach can be used to simulate old film played through a low-quality projector. www.youtube.com/watch?v=NwTU...

Hello, everyone! This time let’s make something a bit simpler, so we can take a break from overly long videos. I will create an infinite tunnel using a so-called Menger sponge, which is a three-dimensional fractal that we'll project onto a two-dimensional plane. www.youtube.com/watch?v=-B_r...

Hello, everyone! On this channel, I’ve been creating Godot shaders of all kinds, but there’s one type I’ve ignored until now - so it’s time to fix that. It’s the shader_type particles, and as the name suggests, we’ll apply it to a GPUParticles3D node. www.youtube.com/watch?v=Fmc1...

Hello, everyone! The shader we’re going to create in this video definitely isn’t one of the most useful effects for game development. So let’s take a look at how to program a four-dimensional cube. www.youtube.com/watch?v=E8xT...

The effect we’ll be creating in this video is something I had been planning for a long time, and now I’ve finally implemented it. As the title suggests, it will be a simulation of raindrops falling onto a water surface, including the typical expanding ripple circles. www.youtube.com/watch?v=0IOI...

Hi everyone! Let’s create a shader that looks like a simple radar, which can be useful for many types of games. It will be entirely generated using lines and other primitive shapes, and we’ll add some animation to it as well. www.youtube.com/watch?v=0O6P...

Hi everyone! I think it’s time for another post-processing effect that we can apply to the entire screen or a selected element. This time, we’ll recreate the look of an old photograph that has yellowed over time and developed other signs of wear. www.youtube.com/watch?v=sC1C...

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. www.youtube.com/watch?v=F-7Q...

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. www.youtube.com/watch?v=i5NP...

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. www.youtube.com/watch?v=1dNx...

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

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. www.youtube.com/watch?v=_2UF...

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

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