I have a scene containing SCNNode models, and a camera. I'd like to generate a depth map render of my scene (from perspective of camera) - something like this: How can this be achieved? Currently looking into SCNTechnique but haven't…
I'm trying to run SceneKit in Xcode, but when I connect my physical device (iPhone 11) the import of SceneKit fails and the following error occurs: "Cannot load underlying module for 'SceneKit'". Can anybody give me a hint how to…

Imported a tiger model into SceneKit, but it is off center? Is this something I can fix? The green/red/blue arrows should be under the model?
I'm using the code below inside a SCNGeometry extension to get the vertex data, and a similar one for .normals, my objective is to create a cloned mesh from the original node to colorize each vertex, but when I try…
