This is a question that gets brought up a lot on the ZDoom and Doomworld forums. Whether its how to import a model, how to animate it, or how to just get the textures to show up correctly, in one way or another this question appears. I've been working on a mod that uses a heavy amount of 3D models and now I feel comfortable enough with GZDoom and Blender that I can write out a tutorial. When I first started importing models into my mod, I had zero knowledge on it. The ZDoom Wiki helps tremendously with 3D models, but not quite enough in my opinion. MODELDEF lacks some documentation on a few properties, like that damned SurfaceSkin property! That being said, you should still refer to it, as it is still the best documented and available resource for all things Doom. Let's begin! Pre-requisites For this tutorial, I'll be using Blender to work with models and animations, and SLADE for working with GZDoom. I'd also recommend ZDL 3 as your Doom Launcher for
