I am looking for a way to get a precise difference between two nodes and their attributes. Lets say you used a SOP to do some point merging, but you are not sure if it did it or not. You could look at the overall point count before and after. But which ones were merged? I would like to have a way to visualize the change in attribute count or value, in the viewport or in another attribute...

Did anyone try something like this?

maybe
