I have been looking through the manual searched google, and I haven't found anything that I think works with nexuiz config of gtkradiant. I am wanting to know how I import a md3 model into gtkradiant. I'm sorry for the "n00bness" of this question but honestly I don't know. If anyone has a site or if they are willing to explain how to do it I would be grateful.
Also, while I am in the question asking mood, how do I add and use a skybox? that is how do I have the sky texture, do i need to set a size somehow, does it set the size for me. Basically I need someone to completely explain the concept of a skybox.
