Working on an inspector plugin.
Anyone know what control this is or if I can extend it?
I’m thinking it’s EditorPropertyResource?
I tried looking through the C++ sprite plugin source code but couldn’t find it referenced.
I feel like it’s an extendable control because ti’s used lots throughout the inspector
