 md3 models are the native format for Q3 engine which Urban Terror uses.

 You need to open in simple text editor (like notepad for example) .qc file with the name corresponding to the model you want to make shine - in our case - lightbulb.qc

 Adding light to models is fairly easy. All You have to do is write a shader for the part that will be emitting light.

 Every good model has obvious light parts textures separated.

 Now we can write a shader in order to emit light from one particular texture. I suggest that shader:

 <br/>When you make .pk3 with .md3 model, you don't&nbsp; include .md3 and .qc files - they are "baked" into compiled map. But you have to copy textures to proper folders in mapobjects directory. That's why paths to the texture in shader are different to the rest of your textures. The two most important parts of the shader are:
