Is there a way in Sprite Kit that I can capture the screen (all the current SKScene rendered nodes) to an SKTexture so that I can apply a CIFilter and then assign the SKTexture back to a new SKSpriteNode?
I know that I can set an SKEffectNode, as the parent of my node tree, apply a filter etc and get the result that way but I really need to have a filtered SKTexture (or SKSpriteNode) that I can reuse later?
EDIT:
Possible solution:
textureFromNode:
Renders and returns a Sprite Kit texture that contains the node’s contents.
Yup that works:
SKTexture *texture = [[self view] textureFromNode:[self scene]];
[blurSprite setTexture:texture];
