Quantize node

Access: Nodes > Math > Quantize

Reduces the input to a fixed number of discrete steps, like a posterize effect applied per channel. At Levels = 2 you get a hard black-and-white threshold; at Levels = 8 you get 8 bands. Very useful for cel/toon shading and debugging gradient flows.

Reduces the input to a fixed number of discrete steps; a per-channel posterize effect.

Quantize node inputs

Input

The continuous input gradient to be posterized into discrete levels.

Quantize node outputs

Output

Quantize parameters

Levels

Defines the number of steps the Quantize node reduces the input by.
