Here’s something which wasn’t available on the old site. It’s a computer console in the classic IDBase style, with a top mounted siren and radar on the back. The really exciting thing about this model is the animated lighting effects, which are achieved through manipulation of the vertex normals of the model. These effects only appear in engines which adhere closely to the original quake rendering model, although no doubt in engines like darkplaces you can make up for this using some kind of shader.
Warning: Most model editors will not preserve vertex normals when editing models, even if your modification only involves the skin. If you do modify this model, you will need to install the python mdl module and the Python Image Library, then run the script supplied in the zip to restore the vertex effects. You will also need the bumpmap file in the same directory as the model and the script – this tells the script which vertices should receive effects.
