usdz file preview doesn't have colors on mac or ipad

I am trying to use the ipad AR capability to visualize some molecules from my simulations.

I created a obj file, and I converted to usdz. If I open the file in xcode everything looks fine. If I use quickview or I move it to the ipad and open it, the colors are missing. I get the same results using usdzconvert 6.1, 6.2, and the export function in xcode.

To convert using usdzconverter I use in usdzconvert 6.1

usdzconvert ./myscene.obj test8.usdz -diffuseColor 1,1,1 -iOS12 -h

or In usdzconverter 6.2 

usdzconvert  ./myscene.obj test5.usdz

I just open the .usdz files from the files app on the ipad or with quick view -i.e. space bar- on the mac.

I think the issue might be that in my scene colors are assigned to vertexes and not to the texture.

Does anyone have an idea on how to proceed?

PS: I am a total noob when it gets to 3D scenes, so probably I am not being particularly clear. I am happy to answer any question you might have.

I had a similar issue before where the rendered usdz model was completely dark when I loaded it into the scene. I fixed it by adding a light source. Try something like this:

let spotLight = SCNNode()
spotLight.light = SCNLight()
spotLight.light?.type = .directional

sceneView.scene.rootNode.addChildNode(spotLight)
