What is the correct way to export meshes including textures etc for use in SceneKit of iOS 8 or even OS X? By the default options I can only export meshes - somehow I don't get textures to work. Also Preview in OS X has trouble opening anything output from Blender/COLLADA so far. Running OS X Mavericks.
For instance, the ship.dae that is included in a template SceneKit project in Xcode 6 has Y for up, whereas stuff exported from Blender has Z up. Maybe this causes errors in the Apple world? Also importing ship.dae then exporting it with default options gives likewise "bad" COLLADA output. I was doing a diff in the input ship.dae and the output one and the differences were rather many so I don't know where to start.
