Using Chat SetAttr you can set creatures. I have had the default settings frequently not work, and being the lazyDM I am, rather than learn what I'm doing wrong, I use the 2 commands listed below to either make a creatures rolls private or not. I know you can do the same thing with the settings you're asking about, but off hand do not know the exact way. Perhaps the commands are listed under the API. I hope this helps to at least point you in a directiuon of help. To make creature public rolls: !setattr --sel --silent --wtype|'' To make creature private rolls: !setattr --sel --silent --wtype|'/w gm ' Also note that when you set the defaults outside the game the way you were trying or had done initially, you must go inside the game to settings and scroll to the bottom to apply those settings and then wit for it to run (3-10 minutes).
