I want to generate a random value for each pixel in the compositor, I tried the noise texture but it gets lower values in average instead of 0.5. 50% of the pixels are completely black.
Far to be enough to build random vectors.

How can I get TRUE randomness on compositor?

  • That's not exactly what I want. The problem is that the noise texture do not create a statically neutral noise. – StackOverflowToxicityVictim Aug 19 '17 at 17:16

Adding a blur of two pixels gives a nice distribution throughout the tone range.

Edit

This is custom color noise setup.
