I need to use the method shown in the linked post for something of my own, but even when using that exact Node layout and Modifier Setting, it ends up breaking Vertex Colors instead- they turn completely black for the object, cannot be edited, and any attempts to modify them using the Value portion of the Capture Attribute Node have no effect.
I'm not understanding why the result is different.
