I would like to preload and use some images for both SpriteKit and SceneKit models (my game uses SceneKit with a SpriteKit overlay), and as far as I can see the only efficient way would be to create and preload SKTexture objects which can be supplied to SKSpriteNode(texture:) and SCNMaterial.diffuse.contents.
The problem is that SKTexture are rendered too bright in SceneKit, for some unknown reason. Here a comparison between rendering an image (from URL) and a SKTexture:
And the code that produces it:
let url = Bundle.main.url(forResource: "art.scnassets/texture.png", withExtension: nil)! let plane1 = SCNPlane(width: 10, height: 10) plane1.firstMaterial!.diffuse.contents = url.path let node1 = SCNNode(geometry: plane1) node1.position.x = -5 scene.rootNode.addChildNode(node1) let plane2 = SCNPlane(width: 10, height: 10) plane2.firstMaterial!.diffuse.contents = SKTexture(image: NSImage(byReferencing: url)) let node2 = SCNNode(geometry: plane2) node2.position.x = 5 scene.rootNode.addChildNode(node2)
This issue was already mentioned in this other post, but since I wasn't notified of the reply from Quinn asking about the feedback number I created at the time, it didn't make any progress.
