Get Specular reflections from IOR
The official Blender documentation provides a method to get the “Specular” value for the PBR-material reflections if the “IOR” value is known. To get the “Specular” value from the “IOR” value, we can use the following equation:
It is not difficult to create it with nodes:
Lighting with textures
In Blender Cycles using common lamps we can illuminate objects with any texture, not just a single color.
Add an object, for example – sphere, to the scene:
shift+a – Mesh – UVSphere
and set a simple diffuse shader to it.
Procedural gradients
Except for the “Gradient Texture” node, we can obtain a gradient factor by using some simple equations. Look for the mathematics with a spherical gradient sample.
- Uniform gradient
Can be created based on a downward-facing cone equation.

Texture pixelization
The simplest way to pixelate texture, procedural or not – get the color from the single pixel and fill the region with required width and height (resolution) with this color.
Here is the gradient texture with red – green – blue colors:
To pixelate it with the first step of resolution we can make some vectors manipulations.
