Hi everybody,
First of all I'm not a 3D expert so please be patient and eventually, sorry for my English which is not my native language.
I'm investigating a problem I met while trying to visualize a Sketchup model within ARkit from Apple.
Basically everything works like expected when you export from Sketchup without the "export edges" enabled. Unfortunatly I need to keep a Sketchup like rendering so I do need the edges.
Exporting the edges works but all meshes with smoothed edges turn full black as if the normals where inverted.
I've done a simple test to be sure it wasn't due to anything strange during the modeling and to show you:
Below into sketchup, the same volume duplicated, one with a rounded edge.
Now first oddity, once exported, osX preview (within Finder) already show the problem, we can see the mesh with rounded and smoothed edge is displayed in full black:
And unfortunately once into sceneKit, same problem.
Anyone has an idea of what's going on here?
Could the Sketchup exporter be the flawed?
Any idea on how I could solve this?
