I have been trying to figure out if there a way to make a "glowing" SCNBox in SceneKit. Unfortunately, I didn't figure it out by myself.
Don't know if the solution is so simple it didn't come into my mind.
Ideas are welcome Thanks
Make an omni light in the same position as your SCNNode. And set the value of the emission of the SCNNode the same colour as your light.
let box = SCNBox.init(width: 1, height: 1, length: 1, chamferRadius: 0.3)
box.materials.first?.diffuse.contents = UIColor.blue
box.materials.first?.emission.contents = UIColor.white
box.materials.first?.emission.intensity = 1.0
let boxNode = SCNNode.init(geometry: box)
boxNode.position = SCNVector3(x: 0, y: 0, z: -10)
self.sceneView.scene?.rootNode.addChildNode(boxNode)
let omniLight = SCNLight()
omniLight.type = .omni
omniLight.color = UIColor.yellow
boxNode.light = omniLight
