How does one go about modifying the Grain Shelf Tool's shape and material? For example, change the shape from a sphere to a box or change the material to glass or metal.

I'm trying to do this with the “Dry Sand” tool. I've only been able to change the color (obj > AutoDopNetwork > grain_color), but not the shape or material.

Specifically, I'm trying to create dozens of glass orbs falling. Is there a better way to do this than the Grain Shelf Tool/Dry Sand Tool?

Thank you!

Generally on most geo nodes you can add materials onto them, and that material will affect all of the geo overall of the the simulation inside of it. I'm not sure of the exact motions of your simulation you are building. But sometimes its easier to create a regular POP net, and copy to points the box, or simple geometry you would like.
