Hello,
Starling has a great feature like different filters. But we cannot use it for spine objects because SkeletonAnimation has zero bounds.
There is the workaround: https://forum.starling-framework.org/topic/apply-starling-filters-to-spine-display-object
Is it possible that you implement this feature (calculate bounds) in SkeletonAnimation class and give us possibility to run filters with simple code e.g.
var animation:SpineAnimation = null;
...
animation.filter = new GlowFilter;
?
It would be great to use filters+spine "out of the box".
If there is a performance issue you can make a flag "update bounds" if user wants to use filters.
Thanks
