Values not adding up correctly

[teidenzero]

Hello, I'm having an issue with the noise generator:

when I generate the noise (supposedly with values between 0 and 1) and I add it to a color, I still get black patches.

Since the black is supposedly 0, this shouldn't happen.
I generated some 0 to 1 noise in Nuke and tested the same thing and this time I was getting the expected result.

I assumed then that the generator must be generating negative values, so I used the old trick of elevating to the power of two in order to make any negative number positive, and then pull the square root to get the values back to their original range, but even this isn't working.

What am I doing wrong?

Use a saturate node this will clamp the values of the noise between 0-1

Hello, as naitoookami kindly pointed out, you'll need to clamp the output of the Noise Generator node to a range of 0-1 by using either the Clamp or the Saturate nodes, otherwise it'll provide negative values, which is expected behavior.
