How can I randomize rotation on the Y axis for each individual point using orientation attribute in Attribrandomize?

Thank you all!

Try using Attribute Adjust Vector SOP to handle this. Depending on how your source object is aligned, you'd want to adjust either the N attribute or the up attribute.

If you did want to randomize orientation fully, you'd want to write to `orient`, not `orientation`.

MOPs Randomize [github.com] is also a pretty user-friendly way of randomizing orientations, among other things. It'll work on template points as well as existing packed primitives.

Somehow this only works with orientation. orient point towards the Z axis.
