The log isn't really helping either

Code:

 

ResourceLocation loc = new ResourceLocation(FlyingFortressBase.MODID, "Cannon.obj");
	try {
		IModel model = OBJLoader.instance.loadModel(loc);
	} catch (IOException e) {
		e.printStackTrace();
	}

 

Log:

I know nothing about loading OBJ models, but just letting you know if you read the stacktrace you could see OBJLoader is in forge.
