I really prefer animating in photoshop where I do all of my art. Now is it possible to import those animations into unity somehow or should I stick to the unity animation process with lets say the method they use in the new 4.3 2D demo.
Yes you can use Photoshop. Create your animation in Photoshop, then use the SpritePlane script to export your frames into a Sprite Sheet that you can use in Unity. On the Sprite’s settings, you change it to multiple, open the Sprite Editor and define your grid size so it can split the sheet up into individual frames for you to use within your Unity animations.
