How to add a property to the property matrix?

Hi guys,

I was wondering how/where I could add a property in the property matrix from the source code. I want to expose the values for distance field scale resolution (because it’s not in there) because I need to bulk edit a few dozen meshes.

A similar question was asked a while ago (below) but I can’t seem to find where to add my code.

Where in the source should I be looking??

EDIT: After searching around the source, I ended up at the PropertyEditorToolkit.cpp but then I’m lost.
