Toolset for converting Ultima Underworld and System Shock 1 levels and objects into other engines. Primarily Unity but earlier versions supported Idtech 4, Source Engine. Most features are geared towards UW1. UW2&SS1 are in cryosleep at the moment but the basic process works for them.
Sample workspace and compiled version using Underworld 1 demo assets http://www.mediafire.com/download/9pz6y5j3sf9l59c/uwdemo_dev.zip
Basic jist of what this does for creating in Unity.
Exports a map into a .fbx model. Extracts the textures in specific order and naming Extracts the game strings Extracts the object and interface art. Extracts the creature animation art and generates a script to make animation assets for them. Similarly for weapons Extracts a big old editor script that re-creates the individual game objects to a T.
Attached UnityScripts for implementing vanilla game behaviour.
The tool is also a general purpose extractor, decompressor and data dumper.
