Is there a way to change radius of a prop_sphere entity? It's set to 12.0 and it seems there are no related datamaps or netprops.

According to this: https://developer.valvesoftware.com/wiki/Prop_sphere
It has a tutorial for when you make a Source Mod to extend the existing prop_sphere entity to include radius.
I.e. there is no net prop because it doesn't exist.
