Randomize Copy to Points

[kiryha]

Hello, 

I need to copy to points same object with some variations. E.g. I have a line with noise, and I want each copy has different noise value.

What is the latest workflow for this? Is this still relevant:

Hi Kiryha,

The latest workflow is to use a for-each loop. Within the for-each loop, you can reference the iteration number. The iteration number will be unique to every point, so you can reference it to offset the noise value.

The video you are watching is still relevant from about 15min onwards.

my take, after copy item to each of your point on the curve by `Copy To Point`, use a Connectivity node

Add an attribute wrangle to random the attribute `offset` which later `Attribute Noise` has that parameter channel, so it will create multiple different noise per connectivity found
