What image format, and what are its dimensions? You don't have any shaders for its texture, right? Is the model and the texture located in the models folder? Are you running your map with sv_pure 0? (reads from folders instead of just pk3s. Which is good) While you should get the md3 to work, I would generally recommend .ase models instead of md3, as you're able to edit .ase files and assign any texture you want. With md3, you'd have to re-export, plus you'd have to have the texture within your "models" folder. If you wonder about .ase files, I've covered that in my new video tutorial about map objects, which I'm currently rendering and should soon be up. On a side note, that's some big pixels
