Looks like applying the filter to each child works perfectly. Thanks for thinking of that!

I don’t have time to answer all the interesting bits, but you might want to look into the new texture canvas feature in the daily builds to let you build the spline frames and store them before you run the game (IE preprocessing them to get all the frames). I am not yet sure if you can use a canvas object in a sprite sheet, but you *probably* can, since they are referenced just like any other image. Think of them as a snapshot you can share between sprites etc.
