The Problem You've seen it or have personally experienced it: You downloaded a cool Doom mod that has multiple files but, you have no idea how to load it. You drag and drop them all onto your GZDoom or Zandronum executable and that seems to work, but something is wrong! The mod isn't loaded correctly, or worse, it failed to load at all! The Solution If you are new to modding Doom or modding in general, this is obviously a huge frustration. You just want to play! One thing I've seen mentioned a lot online is that the mod files aren't in the proper order. A lot of times, a very brief explanation is given, and for a newbie these explanations can be jarring. I won't waste time explaining how to use a batch file or command line to run mods, that's not the scope of this article. Instead, I will show you how to use ZDL, a launcher for Doom.

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
