How to add lighting effect in SKShapeNode
I am using SpriteKit, does SKLightNode can only work with SKSpriteNode? because there is no shadowCastBitMask property on SKShapeNode, I cannot make SKLightNode work with SKShapeNode. Is there a way can make them work together? Thanks!

How to make shadows shorter in SpriteKit?
