Thank you!

I was able to figure it out using the Store Selection node in the first example file you provided.

For anyone who comes across this in the future, here's what I did.

1. Using the same example as before, I converted my binary array into a list of indices representing only the clones I want to be visible. So [1, 0, 0, 1, 1, 0, 1, 0, 1] becomes "0,3,4,6,8".

2. Add a Plane with a Store Selection node as a child.

3. Add a Cloner with a your desired clone object.

4. Set the "Width Segments" and "Height Segments" fields of the Plane to your desired grid size. In my case it's a 3x3 grid.

5. Set the Cloner to "Object" mode and drag the Plane into the "Object" field. Set "Distribution" to "Polygon Center".

6. Give the Store Selection node a name (can be anything) to generate a "Polygon Selection Tag". Drag the resulting tag into the "Selection" field of the Cloner.

7. Hide the Plane and paste the list of indices into the "Selection String" field of the Store Selection node.

That's it.

Thanks again.

Say you have a Cloner with 9 clones in a 3x3 grid like in the image below:

If I wanted to hide clones 1, 2, 5, and 7, I could use the MoGraph Selection tool and chose Hide Selected from the MoGraph menu to get this:

While manually selecting clones works for a small 3x3 grid, it becomes unfeasible for larger setups with tens of thousands of clones.

Is there any way to programmatically define a visibility pattern?

I've played around with Formulas, Python, and the MoGraph Selection node in XPresso, but I can't figure out how to do it.

I feel there must be a way to define an array like this [1, 0, 0, 1, 1, 0, 1, 0, 1] where 1 = "show" and 0 equals "hide", but I'm at a loss.

Any help would be appreciated.
