As part of my scene kit app I display UIImage objects by using a SCNPlane. This works fine with iOS11 and watchOS 4, but the images are not visible with iOS 12 and watchOS 5. This is the case for images that are assets, and also for images created on the fly within the app.
The code I am using is this:
SCNMaterial* material = [SCNMaterial material];
material.diffuse.contents = image;
SCNPlane* plane = [SCNPlane planeWithWidth:image.size.width height:image.size.height];
plane.materials = @[material];
SCNNode* node = [SCNNode nodeWithGeometry:plane];
Am I doing something wrong that I could get away with prior to iOS 12, or is there a bug in iOS 12?
I have tried adding a billboard constraint but that just caused the screen to go completely white when the node was displayed. What might I be doing wrong with that? Does the constraint affect the scale of the node perhaps?
Thanks.
