SceneKit Floor Texture Changed Color in Xcode 8

Question

I have a floor in my SceneKit scene that is suppose to be green based on the texture I have selected for its diffuse property. It worked perfectly in Xcode 7, however, in Xcode 8 it is red and shows up on my device as gray. Here are some screenshots below that help explain this better:

Any and all help is great appreciated.

Answer 1

I suppose this is because your image has a single color channel and SceneKit handles it a R8 texture. Try converting it to RGB (what SceneKit was doing in iOS 9/Xcode7 anyway). And please file a bug.

Answer 2

I recently came across with the same problem and fixed that issue with using JPEG file instead PNG. That might be related with a bug in xCode 8
