Pixel Math

By Light's Store

$15.00 USD

Note: This is a Blender specific ebook about pixel math.

The Problems:

Have you been changing blend types in mix node and hoping to get the correct one? Yes. Even the pros do it in tutorial videos. 😳

Have you wondered how factor differ between the blend modes? There are differences? Never knew anything about them. 😮

Have you read books or websites explaining about blend modes and wonder about the actual inner working, the algorithms and their limitations? I have read Wikipedia and other websites, wasting hours. Still learn nothing. I think of the inner working all the time. Blend modes are math, and computers don’t do magic. 😈

Have you ever wanted to make your own blend mode? Yes. If I’m equipped with the knowledge, I’ll make one and name it with my name. 😆

The Solution:

This ebook.

Pixel Math (noun): Mathematical equations & algorithms which determine color behavior when two or more colors are layered on the same pixel location. Commonly known as blend modes.


  1. Based on real Blender source code.
  2. Full algorithms & simplified versions.
  3. Explained in easy to understand terms.
  4. Nodes examples setup provided.
  5. Small ebook with diagrams, fast to read & understand.
  6. Quick navigation provided.

Useful in shader code, material editor and the compositor editor. Also useful in other software like Substance Painter, Unity 3D, and Unreal Engine.

Reviews: ⭐⭐⭐⭐⭐ 5/5

"Pixel math is an excellent guide to Blender’s powerful node based shading system. I highly recommend it to everyone interested in real time rendering or compositing. You are not going to find a more complete reference anywhere else." —Todor Imreorov

"As both an artist and compositor I would have to recommend 'Pixel Math'. Blend nodes have been covered much but never before was I able to read about them in such depth. Clever writing thats down to the point accompanied with plenty of visual guides made this a very easy to read and understand book. Blend nodes are obvious in their behavior when it comes to screen and multiply however when the other nodes are mentioned it opens up a world of possibilities that have never been covered so in depth before. I cannot recommend this book enough since color control and color math are two of the most important things when it comes to understanding pixel math. Blend modes offer power to generate isolations of values that can change the impact of an entire piece. I am honored to have been allowed the opportunity to get to review it also learn from this. Just the reviewing of this book expanded my pixel math to another level and its all thanks to the genius’ over at BNPR." —Jerry Perkins a.k.a MasterXeon1001

"A handy reference of color blend modes in Blender, this small ebook explains in simple words all the math equations that govern different ways of blending colors. The book will be a good source of information for anyone who has experience of getting mad with color blending options in the compositor, material nodes, and Freestyle line color modifiers." — Tamito Kajiyama a.k.a T.K (Blender Freestyle Developer).
