I understand that to define properties on a topic fragment you have to first compile and OK out of the Topic Info window, re-open it, then adding fragments is possible.

What I am not able to do is add a property pointing to a quest script so I can access it's variables within the fragment.

Is there any way to do this? The variables in question are actually on the same quest as the topic resides, if that makes any difference.

YourQuestScriptName Property QuestScript Auto...     QuestScript.bSomeVar = True...

?

Won't compile. That IS how I would normally do it, but Papyrus Topic Fragments work somewhat differently it seems.

I tried to plug YourQuestScriptName in as the property name and QuestScript as the type in the Add Property dialogue for the fragment, but it will only allow me to resolve it to the name of the quest, which then fails when attempting to access YourQuestScriptName.variables.

This also works instead of creating a property:

(getOwningQuest() as QuestScriptName).iProperty = 1

For QuestScriptName, use the name of the script attached to the quest. Replace iProperty with the property name to be set/accessed.

Hmmm... The property name above would be 'QuestScript', 'YourQuestScriptName' being the type. Haven't worked much with fragments, but can't imagine it working any differently than other scripts. If worse comes to worse, you could use globals.
