SceneKit, Debugging, Albedo

Through much trial and error I found that DAE files that are exported from the Mixamo service render properly when I turn on the debug view under a particular option. There is a popup menu in the scene view debug options (Physics, Bounding boxes, Light influences, Light extents, etc). Those options are clear to me, as they provide visual information about the scene. This can be found when you click on the gear icon when you turn on the debug options under the running program. I so wish I could include a picture in this post. It would be so much easier.Those options can be turned on programmatically under "SCNScenerenderer.showsStatistics"where sceneView.showsStatistics = true, sceneView.debugOptions = [...]What is not clear is the popup to the right of this which include view options (Normals, Geometry Normals, Tangents, Bitangents, Albedo, Roughness, Metalness, AmbientOcclusion)When I turn on "Albedo" the scene is completely viewable, to incluude colors and shading. All of the view options do something but Albedo is the only one that makes the scene visible. I thought those items might be related to either lighting or shading. When I research Albedo, it shows up as physical lighting but I do not know why this is required or how to turn it on programmatically.1) Why is the scene only viewable when I turn on Albedo2) How do I turn this on programmatically3) Can the scene be exported to include this "Albedo" fearure

XCode 10.1, Scene, DAE, Crash

I am using XCode 10.1 on OSX High Sierra 10.13.6 and I get one of two thing happen when I view a DAE (COLLADA) file in XCode.1. The document is not presented with the skin or clothing. I can only see the mesh or skeleton2. XCode unexpectedly quits.I am working on displaying the DAE document on OSX, not iOS. In the case where XCode does not quit, the scene it not presented correctly. I have ensured, looking at the debugging view that I can turn off the wiremesh and skeleton but character is not presented.I have ensured, by looking at the debugging view turning off the wiremesh and skeleton but character is not presented. I find that the files are also not presented correctly in Preview, which I find really strange. My first thought is the file is corrupt however, I have exported DAE fies from MakeHuman, Blender and Mixamo. I'm having a hard time believing all three programs are producing corrupt files. The MakeHuman file caused XCode to terminate but are viewable in Preview without textures. Blender and Mixamo, do not terminate but will only show mesh and skeleton in Preview, XCode and a SceneKit Scene.I have downloaded files that do not render properly.After research I thought that maybe the scntool located in (/Applications/Xcode.app/Contents/Developer/usr/bin/scntool) would fix the file but unfortunately it does not.Is there a tool or process to fix the files so they render properly and not terminate XCode. What do I need to do to make this work properly.

3D Human, articulating characters

I am looking to create a 3D human, articulating character (arms, wrist, fingers, shoulders, head) against a stationary background. This character would be a host or presenter of a show. The character will stand in the same place at all times but it does need to be move in a human way. The character needs to present a multitude of gestures, such as shoulder shruggging, pointing, detailed hand movements, face touching to look inquisitive among other human-like movements and transitions. Which technology is suited for this type of goal? Is this something that is programmable using Swift and can this be done on the fly?
