## Completed Installation of Crystal Space on Klystron Today

In This Posting, I wrote that I had installed “Crystal Space 2.1” on my laptop named ‘Klystron’.

This is an open-source game engine, which competes with “OGRE“, the latter of which is also open-source.

It is not enough just to have the game / rendering engine installed. In order to create content, authors also need to use 3D Model Editors, and the most important of those available in the open source community, happens to be ‘Blender‘, which has its own file-formats for storing projects.

Therefore, one also needs to install the add-on into Blender, which will allow it to export what we have created within it, into Crystal Space format. Fortunately, when I compiled Crystal Space, I did so with full Python support. Blender scripts happen to be written in Python. And in the appropriate shared directory, the Blender add-on could be found.

One word of caution though. In order for this add-on to work properly, Blender must be started with the ‘CRYSTAL‘ environment variable set. This can be done from the command-line, but eventually the authors will want that taken care of automatically.
