I am attempting to use geometry nodes to scatter stuff and I have a handle on the basics of the Point Distribute - Point Scale - Point Instance chain that allows for basic scattering.

However, I am attempting to Add an Attribute Randomize to ensure that my scattered objects aren't all pointing in the same direction. However, while every tutorial I have watched puts "scale" in that Attribute field, I would love to know what else can be placed there.

I know that this is in-process, but I'm sure there has to be a running log of variables. I've tried every permutation I can of 'Z-Rotation' but nothing yet.

My Nodes

Thanks for your attention.

Update: Though it was enough, but no... not yet. I was misreading the screen. When I zoomed in, it wasn't correctly rotated.

Change from Float to Vector, then you can just type in rotation as the attribute, from there you can control the XYZ rotations.

Thanks Duarte. You got me pointed in the right direction. There was just a bit more data that needed to be conveyed to flesh it out. Here is the array:

Corrected Node Array

The keys here, for everyone else that will be inevitably confused by this particular example (rotation variation):

  1. As @simsam noted, ensure that the Attribute is set to: Rotation
  2. Ensure that the Min and Max for X & Y (Values 1 & 2) are set to Zero
  3. Set the Min and Max for Z (Value 3) as the min and max (and thus constitute the degree of variation from the default orientation)

Extrapolating out from that, it looks like standard attribute labels are fine, I just need to remember to also set the appropriate type (in many cases, when dealing with traditional mesh attributes, Vector will be the choice).
