Because of the non-arithmetic operations involved, some devs say they are expensive for the GPU. Others say they are cheap if you have fewer than 100 particles. What do you think?

Animated sparkles are usually created using sprite sheets. I've been experimenting with generating them procedurally using shaders, and it's cool how a few simple mathematical equations can produce such a nice result.

I like this approach because it gives me more flexibility, and I can edit the VFX in real time. What do you think of the result?

I just wanted to share my happiness with you. It took me a while to update the Unity Shaders Bible for Unity 6 using Shader Graph, but it's finally complete.

Over the years, this book has helped over 10k technical artists and game developers around the world, and I'm incredibly grateful for all the support.

The reason I started this project goes back to 2019. At the time, most shader courses were quite expensive, often costing over $170. I wanted to make shader education more accessible, so I created the first edition of the Unity Shaders Bible as an affordable alternative.

Honestly, I never expected it to become so popular, but somehow it did. Seeing so many people learn from it has made all the effort worth it.

Thanks to everyone who has supported the book over the years. It truly means a lot to me.

Hi everyone! Together with several authors, we've been creating technical books covering Unity, Godot, Blender, and Maya. We're working on expanding our library with even more content soon. In the meantime, feel free to check out our books here 🔗 https://jettelly.com/bundles/the-unity-dev-bundle

I'm almost finished writing the Unity Shaders Bible, Second Edition (351 pages so far), and I wanted to add something that could be useful in production, so I created this alpha-cutoff-based transparency system.

The technique is actually pretty simple. I'm using an SDF cylinder that extends from the camera to the character's position, so everything in between gets cut off. I also added a stencil buffer to achieve the flat art style. The same technique can be applied to multiple players to create see-through objects.

I'm currently writing the last chapter of the Unity Shaders Bible, Second Edition, and I created this piece of art to showcase stencils and character-position-based transparency with ShaderLab and Shader Graph.

This video showcases a bundle that includes books on shaders, compute shaders, tool development, animation implementation, and math for graphics. Everything is explained step by step, including the underlying math concepts. Here's the link if you're interested 🔗 https://jettelly.com/bundles/the-unity-dev-bundle

I'm finishing Chapter 4 of the Unity Shaders Bible SE, and I'll be covering these two effects. One is fully procedural, while the second one (the splash effect) uses a particle system.

I'm still missing two more effects for Chapter 4. What other effects do you think would be worth covering?

By the way, this shader is also included in the Godot Shaders Bible package.

If you own the Godot Shaders Bible, you can now download this procedural VFX from the book's package in the Open Source folder. It's free to use in both personal and commercial projects.

Despite the book not being complete yet, the author is releasing new content every month based on readers' feedback. Everything is explained step by step from an artist's perspective. I think this book would be perfect for those who want to get into Technical Art 🔗 https://jettelly.com/store/the-technical-artist-s-guide-to-python-in-maya

I also had to create my own splines because Unity's built-in splines don't support UV coordinates. So, if your mesh is larger than 1 unit, its UV coordinates will fall outside the 0–1 range. What do you think of the result?

By the way, I'll be adding this shader to the Unity Shaders Bible, in case anyone is interested 🔗 https://jettelly.com/store/the-unity-shaders-bible

Hi everyone! I thought this might be useful to some of you. I've been writing books about technical art since 2021, mostly focused on shader development and tool creation. If you're just getting started in this field, check out this book bundle. It might be exactly what you need to get started: https://jettelly.com/bundles/the-unity-dev-bundle

I've been creating these kinds of effects for years, but now I'm turning that experience into a 14-hour video course.

The goal is to show how combining Particle System, Shaders, Compute Shaders, C#, and HLSL allows you to create everything from simple splashes to large-scale ocean simulations.

What do you think of the results? This demo includes Particle System and Shader Graph.
