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.

please check the geometry spreadsheet ones. the al noise require position to apply noise on the grid. if you apply a noise on grid without giving a position it will apply on each point randomly check the spreadsheet of the sampan one.

in sample  2 you are adding position to to the noise then its giving you the fine result
