=== Notes and Comments ===
* CIR files contain 3D meshes including skeletal definitons and material libraries. Since there are no joint positions and rotations given, an [[The Longest Journey ANI|animation file]] is needed to properly display the model.
* The original game engine utilizes Direct3D, thus the model is prepared for a left-handed coordinate system.
* Depending on the representation of the texture in memory, the T coordinate might have to be changed to 1 - T to correctly apply the texture.
* The material colours (probably ambient and diffuse) should only be used if no texture is given (i. e. the texture name is empty).
