SKEffectNode to an SKTexture?

Question

SKEffectionNodes have a shouldRasterise \"switch\" that bakes them into a bitmap, and doesn\'t update them until such time as the underlying nodes that are impa

Answer 1

I think you could try a code like this (it's just an example):

if let effect = SKEffectNode.init(fileNamed: "myeffect") {
    effect.shouldRasterize = true
    self.addChild(effect)   
    ...         
    let texture = SKView().texture(from: self)
}

Update:

After you answer, hope I understood better what do you want to achieve.

This is my point of view: if you want to make a shadow of a texture, you could simply create an SKSpriteNode with this texture:

let shadow = SKSpriteNode.init(texture: )
shadow.blendMode = SKBlendMode.alpha
shadow.colorBlendFactor = 1
shadow.color = SKColor.black
shadow.alpha = 0.25

What I want to say is that you could proceed step by step:

• get your texture
• elaborate your texture (add filters, make some other effect..)
• get shadow

This way of working produces a series of useful methods you could use in your project to build other kind of elements. Maybe, by separating the tasks you don't need to use texture(from:)
