Phong Reflection model in Blender @WannesMalfait

Uploaded September 2020 | Updated September 2026, 3 weeks ago

The Phong Reflection model is a very basic way of lighting a 3D scene. We just look at the diffuse, specular, and ambient lighting. Even though it is basic, the results can still be very pleasing. One advantage is that this method doesn't use any samples, and is really fast on modern hardware.

$Noise texture explained (blender 2.9) The blender node Noise Texture, might be a bit confusing to some. In fact the node is a kind of fractal noise. In this video I give a basic explanation of the noise texture, followed by a detailed and in-depth explanation which covers every input/output socket. At the end of this video I show some other ways you can use fractal noise.
