Sorry, confused the explorer with the property window. Treat “explorer” in my previous reply as the properties panel.
What I meant is that the property panel is not a plugin, it’s a part of the Roblox Studio engine, so it can access non-scriptable properties. A Roblox signed plugin can access RobloxScriptSecurity properties but not non-scriptable ones. So what I meant is that they likely made Lighting.Technology not non-scriptable in preparation for transitioning the properties window to a plugin.
