Anti-Aliased Noise

Recommended Posts

Please look at sample_1 and sample_2.
I don't understand why if I connect node like sample_1 is working but sample_2 is not working.
Can anyone logically explain why we need to use ADD node?
Why if I connect aanoise to P directory is not working properly.

Noises are just a functions that returns a value between 0 and 1 (or -1 1 or -0.5 0.5) depending on the position.
So by connecting a noise directly to the position you overwrite all position values between 0 and 1 (or -1 1 or -0.5 0.5), totaly loosing the original shape.

It's why the correct qorkflow is to add the noise values to the orginal values.
