Ok, I have many models here, but the thing is that I don't know how to convert a 3DS models into Sod files, can someone help me.
I'd recommend Milkshape, but to convert models, you'll need to read through the hardpoint tutorials found on a2files.com, as you need to add specific hardpoints to the model in order to get it to show up using the Armada engine. You can download Milkshape from: chUmbaLum sOft Hope this helps you :)
Ok, but how do you register because I am having no luck what so ever
Once you've downloaded and installed milkshape, open it, then go to the "help" menu, go down and press "about" and you should see a button that says "Register". You'll have to pay about $25-$30 (one of the cheapest if not THE cheapest 3d program for armada and other such games), and then the steps should guide you through from there. Also, you can get the plugins for the various games that you can model for with milkshape from: Milkshape Nif Importer/Exporter plugins, Bridge Commander Downloads, Bridge Commander Modding Tools
