I wanted to post some of the animation I created for 3 Armies. All the animations we done using Flash.
To import the files into Unity 3D I used a program called Sprite Manager 2 (SM2). This is a helpful program if you have all the animation/frames already done. SM2 takes all of your existing frames and compiles them into one image in Unity. This is really helpful if you plan to make games for the iPhone or iPad as it will drastically lower the amount of draw calls that appear on the screen.
