Vertex color in material editor

Hello, i’m trying to do what is seemingly a trivial task. I want to assign per-vertex colors to a mesh and access said vertex colors in the material editor in order for them to show, but I can’t find a node that lets me do that.
I created a procedural mesh using a default sphere static mesh which i copied over, and created an array of constant colors with the same length as the vertex array, like this:

However in the material, the only available vertex color node is used by particles and not meshes:

If i plug a constant color to the Base Color output, it shows in-game just fine:

How are vertex colors possible if so? This is pretty much Hello World level stuff that is dead simple in custom engines that I built, so it seems a bit weird.

Never mind, I figured it out- turns out the order of execution between “Update mesh section” and “Copy Procedural mesh from Static Mesh” needed to be reversed.
