ios - SceneKit view renders as phong instead of physically based materials -


i have several objects in scene, of had "lighting model" of material set physically based.

when run app, view looks nothing scene editor - instead looks more phong materials.

is there root node need change in order have render physically based get-go? i'm new objective-c, i'm not sure if need set lighting model of root node physically based, , if so, how access root node (and furthermore, can root node have lighting model attribute since not renderable).

my models created in zbrush, retopologized , uv mapped in uiviewcontroller, , converted .dae files in blender. possible 1 of programs set material shader phong? wouldn't scenekit editor overwrite , set physically based?

as far can tell, versions of xcode, ios, , scenekit recent enough support pbr.

thank :)
