Version 101 of the Ogier toolset. Used to create levels, surfaces, animations, etc. Recommended that you also install 102.
This seems to be the most functional build of Ogier for use with Enclave. The only things which do not appear to work are the physics simulation recorder, the sound browser, and animation browser. (Sounds can be extracted from your Enclave game files using Dragon Unpacker instead.) You will also want to download the 102 version and install it in a sperate folder as the animation browser and physics simulation recorder are functional there.
