All buildings, terrain, and dungeon spaces, for instance, can be painted down using intuitive and context-sensitive tile paintbrushes. The Toolset was intended to be as intuitive and easy to use as possible. This is the same tool used internally by BioWare to create the official campaigns (and the modules comprising those campaigns can be viewed in the Toolset, once they are played through or otherwise unlocked).
It does not, however, support plug-ins or other third-party extensions.
The Aurora Toolset is a powerful and simple-to-use tool that allows players to change many aspects of Neverwinter Nights, create new modules using themed tilesets and turn many ideas into in-game reality.
