Looking good Hoel. Something is telling me you are going to create some great maps using CD3. I see you are already experimenting with stuff, like the special shape of the castle and the house on top of the tower. And the AA really is a lot better in your map

As for your questions, most are beyond me to answer. I never needed the stuff you are asking, so I have no knowledge of it. I poured most of my knowledge into the tutorials.
The force is strong in you...
