What I saw in this movie was what I think is either done with a macro or a change in the Human Male animations of Fireball, Frost Bolt, etc. Basically anything with a casting time. The movies were by badrasta, and he wont answer any questions about the model edits he did ( mostly to his gear, color change).
You can find the movies at .intro
What I am looking at is when he goes to cast a Fire Ball, his arm will go up to put away his staff. It looks really cool. Oh, and you can see it the most in his 4th video.
If anyone knows how he does this could you please help me make this change to my mage.
