Just done with the new AnimSpriteRenderer. Besides the obvious it has a nice little additional feature: Smooth sprite animations. When having less Sprite frames available than visually pleasant, in some cases it may help to blend frames instead of switching them.
In case of the explosion sprite I used for testing, this feature really pays off. Take a look at the AnimSpriteRenderer demo I’ve uploaded, if you want to see for yourself. Download the .zip file, unpack it and run DualityLauncher.exe.
